Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked beef
- Provides the main protein and savory bulk of the hash.
- Cooked potato
- Adds body and soft texture that holds the hash together.
- Evaporated milk
- Adds moisture and richness to bind the filling as it heats.
- Ritz crackers
- Form a crisp, golden topping when baked with butter.
- Butter
- Adds fat that helps the cracker crumbs brown and taste rich.
The step that matters
Sprinkle the crumb mixture over the top of the casserole.. Crumbs need an even layer so the topping browns uniformly and the filling below is evenly covered and kept moist as it heats.
Swap the onion
How well each one fits the dish's main ingredients (beef, potato, evaporated milk, sauce, pepper, butter):
