Gooseberry Sauce for Mackerel
Ingredients
Directions
Prepare the gooseberries
Remove the stalks and tops from the gooseberries and wash them well.
Cover the gooseberries with cold water and boil gently until tender.
Drain the gooseberries and mix with melted butter and flour.
Finish the sauce
For a smoother sauce, press the gooseberries through a sieve with a wooden spoon.
In a saucepan, stir the pressed gooseberries with sugar and fresh butter over low heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gooseberries
- Provide the main fruit body and tart flavour of the sauce.
- Melted butter
- Adds richness and a smooth, rounded mouthfeel to the sauce.
- Flour
- Thickens the sauce by absorbing liquid as the fruit softens.
- Sugar
- Balances the gooseberries' tartness with sweetness.
- Fresh butter
- Adds final richness and gloss when stirred in over low heat.
The step that matters
Heating the pressed gooseberries over low heat. Gentle heat lets the flour-thickened purée warm evenly and thicken without scorching on the pan base. High heat can burn the butter and sugar and make the sauce taste bitter or catch on the bottom.
Swap the walnut
How well each one fits the dish's main ingredients (butter, flour, sugar):
- Almondfits better
- Macadamia nutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
