Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Egg Sauce

Directions
In a saucepan, mix the potato starch with the melted fat.
Combine this mixture with the milk and cook over medium heat until thickened.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the starch thickens into a sauce.
- Potato starch
- Thickens the milk as its granules swell when heated.
- Fat
- Coats the starch so it blends smoothly and adds richness.
- Hard-boiled egg
- Adds body and chunky texture to the finished sauce.
The step that matters
Thickening the sauce over medium heat. Mixing the starch fully into the melted fat before adding the milk helps prevent lumps. Starch granules swell and thicken the liquid as it heats, so keep the sauce moving over medium heat until it thickens.
Flavor stand-ins for the potato
How well each one fits the dish's main ingredients (milk, pepper, egg):
- Capsicumbetter flavor fit
- Potatothe original
- Asparagusabout as good a flavor fit
- Spinachabout as good a flavor fit
Fit is the average pairing score against milk, pepper, egg. 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).
