Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Grated potato forms the main body and starch that help the kugel hold together.
- Eggs
- Beaten eggs bind the mixture and set it into a firm, sliceable custard.
- Evaporated milk
- Adds moisture and milk proteins that help the kugel turn tender and lightly browned.
- Bacon
- Bacon fat adds richness and savory flavor to the potatoes as they bake.
- Onion
- Chopped onion adds aroma and savory flavor throughout the kugel.
- Butter
- Melted butter adds fat for richness and helps browning on the surface.
The step that matters
Drain the grated potatoes. Grated potato releases water and starch. Removing the excess water before mixing lets the kugel set and brown instead of steaming into a soggy mass.
