What are Mustard Seeds?
Mustard seeds are small but powerful spices, used whole, ground, or as a paste.
They are essential in Indian, European, and North American cuisines, adding pungency and warmth to curries, pickles, sauces, and condiments.
The seeds release their heat when crushed or cooked, due to the enzyme myrosinase converting glucosinolates into mustard oil.
Mustard seeds are also valued for their preservative and digestive properties. They can be toasted, fried, or ground to enhance flavour and aroma in a wide variety of dishes.
