English mustard. The name itself conjures images of Sunday roasts, ploughman’s lunches, and the satisfying sting that accompanies a perfectly crafted sandwich. But why is it so undeniably, memorably hot? What makes English mustard stand head and shoulders (or taste buds) above its milder cousins like Dijon or American yellow mustard? The answer lies in a fascinating combination of ingredients, chemical reactions, and traditional production methods. Let’s delve into the pungent world of English mustard and discover the source of its fiery kick.
The Power of Sinigrin: The Chemical Heart of Mustard Heat
The primary reason behind English mustard’s intense heat can be attributed to a naturally occurring compound called sinigrin. This glucosinolate is found in the seeds of black mustard (Brassica nigra) and brown mustard (Brassica juncea) plants, the very foundation of most English mustard recipes. But sinigrin itself isn’t inherently spicy. It’s a precursor, a sleeping giant waiting to be awakened.
The Myrosinase Enzyme: Releasing the Fire
The magic happens when sinigrin comes into contact with an enzyme called myrosinase. This enzyme is also present within the mustard seeds, but it’s kept separate from the sinigrin within the plant’s cellular structure. When the mustard seeds are crushed and mixed with water (or other liquids), the cell walls break down, allowing sinigrin and myrosinase to mingle.
This is where the chemical reaction begins. Myrosinase acts as a catalyst, breaking down the sinigrin molecule and releasing a volatile compound called allyl isothiocyanate (AITC). This is the real culprit, the fiery component that gives English mustard its characteristic pungency. AITC is the same compound that gives wasabi and horseradish their heat, although in different concentrations and produced from different glucosinolates.
Temperature and Acidity: Influencing the Reaction
The intensity of the heat produced by this reaction is influenced by several factors, including temperature and acidity. A slightly warm temperature generally encourages the enzymatic reaction, leading to a more potent mustard. However, excessive heat can deactivate the myrosinase enzyme, hindering the process and resulting in a milder flavor.
Acidity also plays a crucial role. Acidic environments tend to favor the production of different types of isothiocyanates, some of which are less pungent than AITC. This is one of the reasons why some mustards, like Dijon (which often contains wine or vinegar), have a more complex and nuanced flavor profile compared to the straightforward heat of English mustard.
Black Mustard vs. Brown Mustard: A Question of Intensity
While both black and brown mustard seeds contain sinigrin, black mustard seeds generally yield a more intense and shorter-lived heat than brown mustard seeds. This is due to the specific concentration of sinigrin and the other compounds present in each variety. Historically, English mustard relied heavily on black mustard, contributing to its reputation for potent heat. However, black mustard is more challenging to cultivate and has become less readily available over time. Consequently, most modern English mustard recipes utilize a blend of black and brown seeds, or solely brown seeds, to achieve the desired flavor profile.
The Role of Seed Preparation
The way the mustard seeds are prepared also significantly impacts the final product’s heat. Traditionally, English mustard makers used a process called “milling” or “grinding” the seeds to create a fine powder. This powder is then mixed with water to activate the myrosinase enzyme. The finer the grind, the more surface area is exposed, leading to a more complete and rapid conversion of sinigrin to AITC.
Some producers also use a technique called “de-oiling” the mustard seeds before grinding them. This involves extracting some of the oil from the seeds, which can reduce the overall fat content and potentially concentrate the flavor and heat.
The Secret Ingredients: Enhancing and Balancing the Flavor
While sinigrin and myrosinase are the stars of the show, other ingredients contribute to the overall flavor and heat profile of English mustard.
Turmeric: Adding Color and Complexity
Turmeric is a common ingredient in English mustard. While it doesn’t contribute directly to the heat, it provides a vibrant yellow color and a subtle earthy flavor that complements the pungency of the mustard. Turmeric also has antioxidant properties, which can help to preserve the mustard and prevent it from spoiling.
Wheat Flour: Binding and Textural Influence
Wheat flour, typically used as a binder and thickening agent, also plays a role in the final texture and consistency of the mustard. Different types of flour can affect the overall mouthfeel, influencing how the heat is perceived.
Salt and Spices: Seasoning and Depth
Salt is essential for seasoning and preserving the mustard. Other spices, such as paprika, cayenne pepper, or white pepper, may be added in small amounts to further enhance the flavor and add a subtle hint of warmth, although these are generally used sparingly to avoid overshadowing the inherent heat of the mustard.
Water: The Activation Catalyst
Water is the key to activating the myrosinase enzyme and initiating the conversion of sinigrin to AITC. The amount of water used and its temperature can affect the speed and intensity of the reaction.
The Freshness Factor: Why Freshly Made Mustard Packs a Punch
Freshly made English mustard is notoriously potent, often far more so than commercially produced varieties. This is because the AITC, the volatile compound responsible for the heat, gradually dissipates over time. As the mustard sits, the AITC degrades, resulting in a milder flavor.
The Aging Process: Taming the Flame
Commercial mustard manufacturers often allow their mustard to “age” for a period of time before packaging and selling it. This allows some of the AITC to dissipate, resulting in a more palatable and consistent product for consumers.
Homemade Mustard: Control Over Intensity
Making English mustard at home gives you complete control over the ingredients and the aging process, allowing you to tailor the heat to your personal preference. You can experiment with different ratios of black and brown mustard seeds, adjust the amount of water used, and control the aging time to create a mustard that is perfectly suited to your taste.
English Mustard vs. Other Mustards: A Comparative Analysis
To truly appreciate the heat of English mustard, it’s helpful to compare it to other popular varieties.
Dijon Mustard: Tangy and Aromatic
Dijon mustard, originating from Dijon, France, is typically made with brown mustard seeds, white wine, and vinegar. The addition of wine and vinegar contributes to its characteristic tanginess and complex flavor profile. Dijon mustard is generally less fiery than English mustard, with a more subtle and nuanced heat.
American Yellow Mustard: Mild and Mellow
American yellow mustard, often used as a condiment on hot dogs and hamburgers, is made with mild white mustard seeds, vinegar, turmeric, and other spices. It has a very mild flavor and a bright yellow color. It’s the gentlest of the three, offering minimal heat.

Why does English mustard taste so much hotter than other types of mustard?
English mustard’s intense heat stems primarily from the specific type of mustard seed used in its production: brown mustard seeds (Brassica juncea). These seeds naturally contain higher levels of sinigrin, a glucosinolate compound responsible for mustard’s characteristic pungency. When the seeds are ground and mixed with water, an enzyme called myrosinase breaks down sinigrin, releasing allyl isothiocyanate, the chemical compound that gives English mustard its distinctive and fiery kick.
Unlike other mustards, such as yellow mustard, which often incorporate milder yellow mustard seeds (Brassica alba), English mustard relies almost exclusively on the potent brown seeds. Furthermore, the milling process and the addition of very little or no stabilizing ingredients like turmeric, contribute to the preservation of the allyl isothiocyanate. This ensures the final product retains a concentrated level of the volatile compound, resulting in a significantly hotter and more pungent taste experience.
What role does water play in making English mustard hot?
Water is a crucial component in unlocking the heat of English mustard. It serves as the catalyst for the enzymatic reaction that releases the fiery compounds within the mustard seeds. When water is added to ground brown mustard seeds, the enzyme myrosinase comes into contact with sinigrin, the glucosinolate precursor.
This contact triggers the breakdown of sinigrin, leading to the production of allyl isothiocyanate, the very compound responsible for the characteristic burning sensation. The amount of water used and the temperature at which the reaction occurs can influence the intensity of the heat produced, but water’s fundamental role as the activator of the enzymatic process remains paramount. Without water, the potential heat locked within the mustard seeds would remain largely dormant.
How does the production process of English mustard contribute to its heat?
The production process of English mustard is intentionally designed to maximize the retention of allyl isothiocyanate, the volatile compound responsible for its heat. Unlike some mustard preparations, English mustard typically undergoes minimal processing and contains fewer ingredients that might otherwise neutralize or mask the fiery sensation. The focus is on preserving the natural pungency of the brown mustard seeds.
Grinding the seeds just before mixing with water ensures the myrosinase enzyme is freshly activated, maximizing the release of allyl isothiocyanate. The absence of stabilizing agents like turmeric, commonly found in yellow mustard, also contributes to the perceived heat. Turmeric acts to mildly temper and color the mustard, whilst English mustard recipes focus on the intense taste of mustard seed.
Is there a difference between English mustard powder and prepared English mustard in terms of heat?
Yes, there is a significant difference in heat between English mustard powder and prepared English mustard, primarily due to the timing of the chemical reaction. Mustard powder, in its dry state, contains the precursors for the pungent compounds but not the compounds themselves. The heat is only activated when the powder is mixed with water or another liquid.
When water is added to the powder, the enzymatic reaction begins, and allyl isothiocyanate is produced. However, the heat of freshly prepared mustard from powder is often more intense and sharper than that of pre-made English mustard. This is because the commercially prepared mustard undergoes some processing and storage, which can cause some of the volatile compounds to dissipate over time, diminishing the heat level.
Can the heat of English mustard be reduced?
Yes, the heat of English mustard can be reduced, although it may slightly alter the flavor profile. Adding acidic ingredients, such as vinegar or lemon juice, can help to slow down or inhibit the enzymatic reaction that produces allyl isothiocyanate. This can temper the intensity of the heat and create a milder flavor.
Mixing English mustard with other ingredients, such as honey, cream, or mayonnaise, can also help to dilute the concentration of the pungent compounds, effectively reducing the perceived heat. These additions introduce competing flavors and textures that balance the fiery sensation, making the mustard more palatable for those sensitive to spice.
Does the age of English mustard affect its heat?
Yes, the age of English mustard can affect its heat, but in a somewhat complex way. Freshly prepared English mustard, especially if made from mustard powder, often exhibits the most intense heat due to the freshly released allyl isothiocyanate. However, over time, particularly if improperly stored, the volatile compounds responsible for the heat can gradually dissipate.
Therefore, older English mustard may lose some of its initial fiery potency. However, the development of other flavor notes can also occur as the mustard ages, resulting in a more complex, albeit less intensely spicy, taste. Proper storage in a cool, dark place, tightly sealed, can help to slow down the loss of heat and preserve the overall quality of the mustard.
Are there any health benefits to eating English mustard?
Yes, there are several potential health benefits associated with consuming English mustard, primarily due to the compounds found in mustard seeds. Mustard seeds are a good source of selenium and magnesium, both essential minerals that play important roles in various bodily functions. Additionally, they contain glucosinolates, which have been linked to potential anti-cancer and anti-inflammatory effects in some studies.
The allyl isothiocyanate, responsible for the mustard’s heat, is also being investigated for its potential antimicrobial and antioxidant properties. While more research is needed to fully understand the extent of these benefits, incorporating English mustard into a balanced diet may contribute to overall health and well-being. Remember to consume in moderation as part of a balanced diet.
