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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter and flour paste
- Thickens the stock into a gravy as the starch swells when heated.
- Mushrooms
- Provide the main body and earthy flavour of the stew.
- White stock
- Forms the liquid base that the thickened gravy is built on.
The step that matters
Add the paste to the stock to thicken it.. Flour must be fully mixed into the fat and then whisked into hot liquid to prevent lumps. Stirring as it heats lets the starch swell evenly and thicken the gravy smoothly.
Swap the lemon
How well each one fits the dish's main ingredients (pepper, butter, flour, mushroom):
- Lemonthe original
- Plumfits about as well
- Limefits less well
- Cherryfits less well
Fit is the average pairing score against pepper, butter, flour, mushroom. Candidates are from the same food group and used in at least 100 recipes.
