Why it works: Flour and butter 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 ↓
To Fry Sweet-breads
Ingredients
Directions
Prepare the sweetbreads
Wash the sweetbreads and boil them in salted water for about 15 minutes.
Remove the sweetbreads from the water and let them cool.
Skin and cut the sweetbreads in half, then season them with pepper and salt.
Fry and serve
Dust a little flour over the sweetbreads and fry them slowly in equal parts of butter and lard until golden brown.
Place the fried sweetbreads on a dish.
Dust a little flour into the pan with the fat, stir well, and pour in the hot water.
Season the gravy with salt and pepper, and once it boils, pour it over the sweetbreads and serve hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Form the main body of the dish, becoming tender when boiled and then crisp-browned when fried.
- Flour
- Forms a light coating that browns in the fat and thickens the pan gravy.
- Butter and lard
- Fat for frying that browns the coating and adds rich flavor.
- Hot water
- Liquid that, combined with the pan flour and fat, makes the gravy.
The step that matters
Fry slowly in the butter and lard. Slow frying over moderate heat lets the flour coating turn golden brown without burning, while the sweetbreads cook through and keep a tender interior.
