Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb
- Provides the main meat, which becomes tender through long slow cooking in the stock.
- Butter
- Enriches the sauce and carries flavour while the flour is cooked into a roux.
- Flour
- Thickens the stock into a smooth sauce when cooked briefly with the butter.
- Egg yolks
- Enrich and thicken the sauce when stirred in off the heat, giving it a silky texture.
- Cream
- Adds richness and smoothness, softening the sauce alongside the egg yolks.
- Mushrooms
- Add earthy flavour and moisture to the stew as they cook.
The step that matters
Adding the egg yolk and cream. Egg yolks thicken when heated gently but can scramble if the stew is boiling. Stir them in off the heat, or over very low heat, to keep the sauce smooth and creamy.
