Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Tripe
- Forms the main body of the stew and becomes tender through slow cooking.
- Flour
- Thickens the milk into a smooth, lightly bodied sauce.
- Milk
- Forms the creamy liquid that simmers with the tripe and sets the stew's mild flavour.
- Onion
- Adds sweetness and savoury aroma as it softens in the milk.
The step that matters
Thicken with flour mixed with cold milk. Flour added directly to hot liquid clumps into lumps. Mixing it first with a little cold milk makes a smooth slurry that disperses evenly and thickens the stew without graininess.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (flour, onion, pepper, milk):
- Turmericfits better
- Cardamomfits about as well
- Garlicfits about as well
- Parsleythe original
Fit is the average pairing score against flour, onion, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
