Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cheese Sauce with Roast Peppers
Ingredients
Directions
Make the sauce
Add all ingredients to a blender or food processor and blend until smooth.
Then add to a saucepan and heat on medium with continuous stirring until barely boiling and sauce is thick and smooth.
Serve
Serve immediately, if not sooner.
If you reheat, first add a little water, stir, then heat.
Great on anything on which you'd use a cheese sauce or it's even good by itself.
Note: the original recipe calls for pimientos, but roast peppers give it a much better flavor.
Nutrition, whole recipe (rough)
Counts 6 of 8 ingredients. The other 2 aren't in our nutrition table and add nothing above, so the real totals are higher.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Instant mashed potatoes
- Thickens the sauce and gives it a creamy body as they absorb liquid.
- Nutritional yeast
- Provides a savory, cheese-like flavor that stands in for dairy cheese.
- Arrowroot
- Thickens the sauce to a smooth, glossy consistency when heated.
- Roast peppers
- Adds sweet, smoky pepper flavor and color to the sauce.
- Lemon juice
- Adds acidity that brightens the flavor and balances the savory notes.
The step that matters
Heating with continuous stirring. Arrowroot thickens only when heated and can clump or scorch if left unstirred on the heat. Stirring keeps starch evenly dispersed, so the sauce turns smooth and thick rather than lumpy. Stop at barely boiling, since prolonged boiling can thin starch-thickened sauces.
Swap the arrowroot
How well each one fits the dish's main ingredients (potato, pepper, onion, lemon, chicken):
- Capsicumfits better
- Okrafits better
- Spinachfits better
- Arrowrootthe original
Fit is the average pairing score against potato, pepper, onion, lemon, chicken. Candidates are from the same food group and used in at least 100 recipes.
