Why it works: Onion and peas are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 5,460 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Heart Sweetbreads
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
Place green onions in the center of a dish and cover with bacon.
Moisten with stock and cover with buttered paper.
Braise
Boil sweetbreads on the stove, then transfer to a 350°F (175°C) oven or a moderate fire.
Braise for about 20 minutes, basting frequently with the liquid.
Glaze and serve
Remove the lid and paper, then return to the oven to dry and glaze the surface.
Serve on a bed of stewed peas.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green onions
- Lie under the sweetbreads and perfume the dish as they cook.
- Bacon
- Thin layers of fat baste the meat and add savory flavor as they render.
- Stock
- Provides moisture for braising and forms the liquid used for basting.
The step that matters
Basting during the braise. Basting returns the cooking liquid over the sweetbreads, keeping the surface moist and the meat tender while the braise is covered and gently cooking.
Swap the peas
How well each one fits the dish's main ingredients (onion, butter):
- Sesamefits better
- Peanutfits better
- Almondfits better
- Peasthe original
Fit is the average pairing score against onion, butter. Candidates are from the same food group and used in at least 100 recipes.
