Why it works: Raisin and flour match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sultana raisins
- Plump up when cooked and add chewy sweetness and body to the sauce.
- Flour
- Thickens the sauce as its starch swells in the hot liquid.
- Sugar
- Adds sweetness and balances the tartness of the lemon.
- Lemon peel
- Adds bright citrus aroma and a little acidity to the sauce.
- Sherry or brandy
- Adds a warm, aromatic flavour that carries through the sweet sauce.
The step that matters
Boil the mixture for the full 10 minutes. Flour starch only thickens fully when it is heated close to boiling and its granules swell. Stopping early leaves the sauce thin and tasting raw and floury.
Swap the lemon
How well each one fits the dish's main ingredients (raisin, flour, sugar, sherry):
- Vanillafits better
- Figfits better
- Applefits better
- Lemonthe original
Fit is the average pairing score against raisin, flour, sugar, sherry. Candidates are from the same food group and used in at least 100 recipes.
