Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries flavour while it forms the base with the flour.
- Flour
- Cooked in the butter, it thickens the stock into a smooth, lightly bodied sauce.
- Stock
- Forms the liquid base of the sauce, giving it savoury depth.
- Sardines
- Supply the main fish flavour, and the chopped fish is served under the strained sauce.
- Lemon rind
- Adds bright aromatic oils that lift the richness of the fish and sauce.
The step that matters
Cooking the flour in the butter. Stirring the flour into melted butter and cooking it gently for a few minutes cooks out its raw starch taste and lets it thicken the stock evenly. Skipping this stage or rushing it can leave a floury flavour and lumps.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, shallot, nutmeg, pepper):
- Lemonthe original
- Limefits about as well
- Avocadofits less well
- Raisinfits less well
Fit is the average pairing score against butter, flour, shallot, nutmeg, pepper. Candidates are from the same food group and used in at least 100 recipes.
