Why it works: Capsicum and cucumber match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stale bread
- Provides a dry, firm base that holds the toppings without going soggy.
- Butter
- Adds fat and a moisture barrier so the toppings sit well and the bread stays flavourful.
