Why it works: Pepper and clove match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Pickled Walnuts
Ingredients
Directions
Rub the walnuts with a coarse towel.
Soak the walnuts in saltwater strong enough to float an egg for two weeks.
Drain the walnuts and place them in a kettle with enough fresh water to cover them.
Let the walnuts stand in the water for twelve hours, keeping them hot but not boiling.
In a separate pot, combine the vinegar, pepper, cloves, and mace.
