Why it works: Parsley and pepper 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 ↓

To Roast a Rabbit

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat your oven to 400°F (200°C).
Prepare the rabbit by casing and trussing it.
Roast the rabbit, basting it with good butter.
Dredge the rabbit with a little flour to froth it when ready.
Boil the liver with chopped parsley until cooked.
Melt some butter and mix in half the liver and parsley; toss over heat.
Pour the mixture into the serving dish and garnish with the remaining liver and parsley.
Season the sauce with a little pepper, salt, and a grate of nutmeg.
