Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Provolone cheese
Melts over the hot vegetables to bind the sandwich together and add richness.
Olive oil
Coats the vegetables so they brown and char on the grill rather than drying out.
Red pepper
Softens and sweetens as it chars, adding moisture and savoury depth.
Zucchini
Turns tender and lightly charred on the grill, adding moisture to the filling.
Pesto
Adds herbal, fatty flavour that carries into the bread and the filling.

The step that matters

Grilling the vegetables until crisp-tender and lightly charred. Cooking too long turns the zucchini and pepper soft and watery, which soaks the bread. Stopping at crisp-tender keeps their texture and lets light charring add browned, roasted flavour through the Maillard reaction.

  2. Capsicumbetter flavor fit
  3. Eggplantbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against pepper, olive, oregano, bread, provolone cheese. 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).
