Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 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
- Hot cooked rice
- Forms the bulk of the ball and gives a soft, tender interior.
- Sharp cheddar cheese
- Melts into the mixture and adds rich, savoury flavour and binding.
- Eggs
- Bind the mixture so the balls hold their shape while frying.
- Soft breadcrumbs
- Form a crisp, golden coating that protects the balls in hot oil.
- Creole mustard
- Adds sharp, tangy flavour that cuts through the rich cheese.
The step that matters
Chill the mixture before forming. A cold, firm mixture holds its shape when rolled and fried. Warm, soft mixture is more likely to crack or fall apart in the oil.
