Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the sauce and provide its acidity and flavour.
- Cracknel biscuits
- Soaked and sieved, they thicken the tomato purée into a smooth sauce.
- Butter
- Adds richness and flavour, and is used to fry the mushrooms for browning.
- Cream
- Adds richness and a smoother, milder texture to the finished sauce.
- Mushrooms
- Fried in butter, they brown and add savoury, earthy flavour around the sauce.
The step that matters
Stir until the mixture boils. Once the biscuit-thickened tomato mixture reaches a boil it thickens and cooks through. Cream should be added after this, since prolonged boiling can cause dairy to separate.
