Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the ring, giving it body and a starchy, tender texture when baked.
- Eggs
- Bind the grated potatoes together and help the ring set firm as it bakes.
- Butter
- Adds richness and moisture, and helps the surface brown in the oven.
- Milk
- Adds moisture that bakes into the custard-like body of the ring.
- Cheddar cheese
- Melts over the top and browns, adding savory flavor and a golden crust.
The step that matters
Bake until the cheese has melted and browned. The cheese goes on only after the ring has baked, so it needs a second, shorter bake. Too little time leaves it unmelted, while too long can dry the ring and scorch the cheese.
Swap the onion
How well each one fits the dish's main ingredients (potato, butter, egg, milk, cheddar cheese):
- Chivefits better

- Capsicumfits about as well
- Onionthe original
Fit is the average pairing score against potato, butter, egg, milk, cheddar cheese. Candidates are from the same food group and used in at least 100 recipes.
