- Asparagusbetter flavor fit
- Onionthe original
Fit is the average pairing score against pepper, lemon, egg, olive. 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).
