Why it works: Pepper and mustard are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 15,430 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Essence of Mushrooms
Ingredients
Directions
Wash and peel the mushrooms, then cut them into small pieces.
Layer a quarter-inch thick of the minced mushrooms in a new earthenware jar, sprinkling with fine salt.
Press down with a light weight, using a reversed saucer if possible.
Pound the mixture together the next day and let it stand for 48 hours, stirring every 6 hours until it becomes a puree.
Add black pepper and mustard seed, then boil in a bain-marie for 3 hours.
Run the mixture through a fine wire sieve and decant the clear part carefully.
Add a spoonful of spirit before corking and sealing the jar tightly.
