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 ↓
Calf’s Liver, Baked
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash and dry the liver, then lightly flour and pepper it.
Lay a few slices of fat bacon on top of the liver.
Bake and serve
Cook in a moderate oven at 350°F (175°C), basting occasionally with the bacon fat.
When nearly done, remove the bacon and sprinkle the liver with breadcrumbs.
Brown the surface nicely and serve with plain gravy made in the pan or a sauce of your choice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Forms the main body of the dish, cooked gently so it stays moist inside.
- Flour
- Lightly coats the liver so its surface can take on color and hold moisture.
- Fat bacon
- Melts and bastes the liver, adding fat that keeps it moist and flavorful.
- Breadcrumbs (in the method)
- Form a crisp, browned crust on the surface during the final minutes of baking.
The step that matters
Basting with bacon fat. Liver is lean and dries out and toughens quickly in heat. Regular basting with fat keeps the surface moist and helps the bacon flavor penetrate, so the liver stays tender rather than tough.
