Why it works: Beef and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and 17,091 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the base
In a stewpan, combine the bacon, beef suet, and butter.
Add the lemon juice, bay leaves, cloves, carrots, onions, and water.
Cook and strain
Simmer gently, stirring often, until the fat is melted and water evaporates.
Pour in more liquid than needed for the dish to be cooked.
Boil softly until all ingredients release their flavor.
Season with salt if needed.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fat bacon
- Supplies rendered fat that carries flavor and gives the base its richness.
- Beef suet
- Adds solid fat that melts slowly, enriching texture and mouthfeel.
- Butter
- Contributes fat and a rounded dairy flavor to the cooking medium.
- Lemon juice
- Adds acidity that brightens the rich fats and balances their heaviness.
- Onions
- Release sugars and aromatic compounds as they cook, adding savory depth.
- Carrots
- Contribute natural sweetness and body to the flavored fat.
The step that matters
Simmer gently and stir often. Fat and water mixtures can scorch or spatter if heated too hard. Gentle heat lets the water evaporate slowly and the solids flavor the fat without burning, which would make the result bitter.

Fit is the average pairing score against beef, butter, clove, carrot, onion. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
