Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spinach (in the method)
- Forms the body of the dish once chopped fine and cooked down in the sauce.
- Butter
- Adds richness and a smooth mouthfeel to the sauce and the spinach.
- Flour
- Thickens the melted butter into a roux that gives the sauce body.
- Veal broth or gravy
- Supplies the liquid that, combined with the roux, forms the sauce.
The step that matters
Adding the broth or gravy. Adding liquid gradually while stirring keeps the roux smooth, so the sauce thickens evenly without lumps.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
