Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
A Meat Hash
Ingredients
Directions
Prepare
Pour boiling water over the tomatoes to remove the skins, then slice them.
Chop the onion and add it to a stew pan with the tomatoes.
Add sugar, butter, salt, pepper, and cold water to the pan.
Shave the meat as thin as possible and dust it with flour.
Cook
Cook the mixture slowly for one hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture of the hash as they break down during cooking.
- Onion
- Adds savory depth and aroma to the base as it softens.
- Butter
- Adds richness and fat, giving the mixture a smoother mouthfeel.
- Meat
- Forms the savory protein element of the hash, with flour helping it thicken the mixture.
The step that matters
Cook the mixture slowly for one hour. Gentle, low heat lets the tomatoes and onion break down and the flour-dusted meat thicken the liquid without scorching on the bottom of the pan.
