Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Puff pastry
- Forms the golden, flaky, crisp shell that holds the filling.
- Lambs' tails
- Provide the main meat, which becomes tender through slow stewing in liquid.
- Butter
- Adds richness and fat that carries flavour and gives the stew a smooth mouthfeel.
- Egg yolks
- Thicken the sauce and add richness when stirred in without boiling.
- Cream
- Adds smoothness and richness to the sauce, softening its texture.
The step that matters
Stirring in egg yolks and cream. Egg yolks can scramble and curdle if the sauce boils after they are added. Stir them in just before serving, off the heat or at a gentle warmth, so the sauce thickens smoothly.
