Mix and bake

  1. Add the flours, salt, and golden syrup to the mixture.

  2. Beat the mixture until stiff.

  3. Pour into a buttered tin and bake at 350°F (175°C) for 30 minutes.

Serve

  1. Smooth the top with a spoon dipped in milk before serving hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rye flour
Adds earthy flavour and a tender, less elastic structure than wheat flour.
Wheat flour
Supplies gluten to give the cake more structure alongside the rye.
Sour milk
Its acidity reacts with baking soda to produce gas, helping the cake rise.
Baking soda
Reacts with the acid in the sour milk to release carbon dioxide for rising.
Golden syrup
Adds sweetness, moisture and a deeper colour through browning.

The step that matters

Combining baking soda with sour milk until bubbly. The soda and acid react immediately to release carbon dioxide gas. The batter should be mixed and baked promptly so the gas is trapped in the batter and lifts the cake rather than escaping.
