Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Kidney Beans with Sauce
Ingredients
Directions
Soak the beans overnight.
The next day, boil the beans in salted water until soft. Drain.
In a saucepan, combine the first gravy from roast veal with butter and minced onion.
Boil for five minutes, then strain through a sieve, pressing the onion.
Season the sauce with pepper, salt, and chopped parsley.
Pour the sauce over the beans and simmer for fifteen minutes, covered.
Drain off half of the liquid and serve in a covered dish.
