Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
To Roast Wild Fowl
Ingredients
Directions
Remove gills from the wild fowl.
Season the inside with pepper, coarse sea salt, and a piece of butter.
Place an onion and hot water in the dripping pan and baste the fowl for the first 10 minutes.
Remove the pan and baste constantly with butter until cooked.
Serve with a squeeze of lemon, pepper, and salt on the sliced breast.
