Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parsnips
- Form the bulk of the balls and provide the main flavor and body.
- Butter
- Adds richness and moisture to the mashed parsnips.
- Egg
- Binds the mixture so the balls hold their shape, and helps the coating adhere.
- Milk or cream
- Adds moisture and softness to the mixture.
The step that matters
Let the mixture cool before adding the egg. Adding beaten egg to a hot mixture can scramble it and make it loose and uneven. Cooling first lets the egg blend smoothly and bind the balls so they hold their shape while frying.
Swap the parsnip
How well each one fits the dish's main ingredients (butter, pepper, milk, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Parsnipthe original
Fit is the average pairing score against butter, pepper, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
