Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Broiled Sweetbreads
Ingredients
Directions
The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Split the sweetbreads.
Season with pepper and coarse sea salt.
Rub with butter and sprinkle with flour.
Broil
Broil over a hot fire (400°F / 200°C) for twenty minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; they become tender and lightly crisp on the surface under high heat.
- Butter
- Adds fat and richness, and helps the surface brown during broiling.
- Flour
- Dusted on the surface, it helps form a light crust that browns during broiling.
The step that matters
Broil over a hot fire. Sweetbreads need strong, direct heat to brown the outside before the inside overcooks. Too low a heat or too long a time can leave them dry and rubbery, while a properly hot fire gives a crisp, golden surface and a tender interior.
