Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrow
- Forms the main body of the stew, becoming tender as it cooks gently in broth.
- Egg yolk
- Thickens the sauce gently when stirred in, giving it a smooth, creamy body.
- Butter
- Adds richness and fat that carries flavour and helps the marrow toss without sticking.
- Lemon juice
- Adds acidity that brightens the sauce and balances the richness of the yolk and butter.
The step that matters
Adding the egg yolk and lemon. Egg yolk thickens when heated gently, but if the sauce gets too hot or boils after the yolk goes in, it can curdle or scramble. Stir it in off the heat or over very low heat.
