Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Mix the rye and wheat flour together.
Combine the baking soda with the sour milk and stir until bubbly.
Mix and bake
Add the flours, salt, and golden syrup to the mixture.
Beat the mixture until stiff.
Pour into a buttered tin and bake at 350°F (175°C) for 30 minutes.
Serve
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.
