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 ↓

What each ingredient does
- Sultana raisins
- Release sugars and fruity flavour into the liquid as they soften, giving the sauce its body and sweetness.
- Flour
- Thickens the liquid as its starch swells when heated.
- Sugar
- Adds sweetness and rounds out the flavour of the sauce.
The step that matters
Adding the flour and sugar mixture to the broth. Flour clumps when it meets hot liquid unless its grains are separated and dispersed. Mixing it with sugar first helps spread the particles, so the sauce thickens smoothly instead of forming lumps.
