Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,036 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)

- Peasabout as good a flavor fit
Fit is the average pairing score against butter, parsley, chive, pepper, lemon. 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).
