Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the bulk of the spreadable vegetable mixture, adding body and moisture.
- Carrots
- Add sweetness and color to the vegetable mixture as it cooks.
- Potatoes
- Starch thickens the mixture as it cooks down, giving a spreadable texture.
- Parsnips
- Add sweetness and a mellow, earthy flavor to the vegetable mixture.
- Egg yolk
- Binds the chopped vegetables together so the mixture holds on the toast.
The step that matters
Cook over low heat until thickened. Gentle heat lets the vegetables soften and release moisture slowly, so the mixture thickens evenly without scorching. Egg yolk added before cooking can curdle if the heat is too high, so keeping it low protects the texture.
