Mustard powder is made from mustard seeds. Known since ancient times, mustard paste gained its name "mustard" from the French and owes it to the practice of mixing crushed seeds with wine, that is, with must.

Mustard powder needs to come into contact with water to release its flavor. Therefore, before use, it should be mixed with a little water, milk, or vinegar, and after letting the mixture sit for a while, it can be added to the food.
