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 ↓
Mushroom Sauce for Beefsteak
Ingredients
Directions
Take one can of mushrooms, and if large cut them up a little.
Place in a skillet with one tablespoonful of butter.
Let fry to a light brown.
Add one and a half cups of soup stock, if you have it, if not, use hot water, and three tablespoons of tomato catsup, salt and pepper to taste.
Thicken a very little with flour.
Let boil up thoroughly and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms (in the method)
- Provide the main body and savoury flavour of the sauce.
- Butter
- Fat for frying the mushrooms, helping them brown lightly and add richness.
- Soup stock
- Forms the liquid base of the sauce.
- Tomato catsup
- Adds sweetness, acidity and colour to the sauce.
- Flour (in the method)
- Thickens the liquid into a sauce as it boils.
The step that matters
Thicken a very little with flour. Flour must be stirred in evenly and the sauce boiled through, because starch only thickens fully once heated to boiling. Adding too much flour makes it pasty, while too little leaves it thin.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Tomatothe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
