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 mixture and give it a soft, moist body.
- Butter
- Adds richness and moisture to the mash and helps the top brown.
- Bread crumbs
- Absorb moisture and add body, and form a crisp topping when baked.
- Egg
- Binds the mashed mixture and sets during baking to hold its shape.
