Why it works: Spinach and pepper are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 3,400 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Fried Liver and Bacon with Spinach
Ingredients
Directions
Prepare
Wash the spinach thoroughly, trim the roots and tough stalks, and soak in cold water.
Slice the calf's liver into ½‑inch thick pieces, pour boiling water over it, and let it cool to remove the skin.
Dry the liver with a cloth and roll it in seasoned flour.
Slice the bacon very thin and fry it in a pan until it begins to crisp.
While the bacon cooks, drain the spinach and boil it in salted water for about 5 minutes until tender.
Drain the spinach and place it in cold salted water.
Once the bacon is crisp, remove it from the pan and keep it warm.
Fry and serve
Fry the liver in the bacon drippings until browned on both sides, seasoning with salt and pepper.
Place the cooked liver on a warm dish with the bacon.
Drain the spinach again, stir it in the frying pan with the drippings until hot, then serve it on a platter.
Top the spinach with the liver and bacon, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Main protein; boiling water and cooling loosen the skin, and flour coating helps it brown.
- Bacon
- Provides fat and drippings that brown the liver and add smoky, salty flavour.
- Spinach
- Cooked to tenderness, it forms the bed and absorbs flavour from the bacon drippings.
- Flour
- Seasoned coating that helps the liver brown in the drippings.
The step that matters
Frying the liver. Liver is delicate and overcooking it makes it dry and grainy. Brief, high heat in the drippings browns the outside while keeping the inside tender.
