Why it works: Cucumber and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 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
Preheat the oven to 350°F (175°C).
Place green onions in the center of a dish.
Cover with thin layers of fat bacon.
Moisten with about 2 cups of good stock.
Cover with a round of buttered paper.
Cover the dish with a lid.
Bring the sweetbreads to a boil on the stove.
Braise
Transfer to the oven or a moderate fire.
Add live embers on the lid if using a fire.
Braise for about 20 minutes.
Baste frequently with the cooking liquid.
Remove the lid and paper.
Return to the oven to dry the surface.
Glaze and serve
Glaze the sweetbreads.
Serve on a bed of stewed peas or other vegetables.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- The main protein; it is cooked gently so it stays tender and moist.
- Fat bacon
- Melting fat slowly bastes the sweetbreads and adds savory flavor to the dish.
- Good stock
- Moist cooking liquid that braises the sweetbreads and forms the base for basting.
- Butter
- Buttered paper keeps the surface from drying and adds richness to the braise.
- Green onions
- Aromatics that sit beneath the sweetbreads and perfume the braising liquid.
The step that matters
Drying the surface after braising. Removing the lid and paper and returning the dish to the oven lets surface moisture evaporate so the glaze adheres and browns rather than running off.
Swap the onion
How well each one fits the dish's main ingredients (butter, peas, asparagus, beans, cucumber, lettuce):
- Beetrootfits better
- Cauliflowerfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against butter, peas, asparagus, beans, cucumber, lettuce. Candidates are from the same food group and used in at least 100 recipes.
