Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cream cheese
- Adds richness and a creamy body to the chopped filling.
- Egg
- Thickens the cooked sauce as its proteins set with gentle heat.
- Flour
- Thickens the sauce and gives it a stable, spreadable body.
- Hard-boiled eggs
- Add firm, mild bulk to the chopped filling.
- Vinegar
- Adds acidity that sharpens the flavor of the filling.
The step that matters
Cook the mixture over low heat, stirring constantly. The egg and flour thicken the sauce as they heat. Low heat with constant stirring prevents the egg from scrambling and lumps from forming, giving a smooth, spreadable filling.
