Why it works: Chicken and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 17,814 recipes. Both carry gamma-nonanolactone, which smells coconut, sweet. The science ↓
Smothered Chicken
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Clean the chicken thoroughly.
Split the chicken down the back and place it breast up in a covered roasting pan.
Slice the onion and place it under the chicken.
Season the chicken all over with pepper and coarse sea salt.
Bake
Add 2 cups of water to the pan, cover it, and place it in a 350°F (175°C) oven.
Bake for 1 to 1.25 hours, renewing water as necessary, until golden brown.
