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 batter, giving a starchy, sliceable body with crisp edges.
- Eggs
- Bind the grated potatoes and set during baking to hold the kugelis together.
- Carnation milk
- Adds moisture and richness so the potatoes stay tender inside.
- Butter
- Adds fat for flavor and golden browning on the surface.
- Onion
- Sautéed to bring sweetness and aroma to the batter.
The step that matters
Bake until the center is done. The eggs must fully set in the middle, or the kugelis will stay wet and loose. Grated potato holds a lot of water, so the center needs enough time to cook through while the outside browns.
