Why it works: Rye and wheat match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 404 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
One Cup and a Half of Sour Milk
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 the batter
Sift the rye meal, then sift the Indian meal with the salt.
Add the wheat flour and baking soda, sifting the soda twice with the flour.
Stir in the molasses, then add the sour milk.
Butter twelve small cup-shaped cake pans and fill them about halfway.
Steam and bake
Place the pans in a large tin steamer over boiling water, ensuring the steamer is covered tightly.
Steam for one hour and forty minutes.
Remove from the steamer and place in a 350°F (175°C) oven for 8 to 10 minutes, adjusting time if the oven is very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye meal
- Provides the main body and earthy flavour of the cake's crumb.
- Indian meal
- Adds coarse texture and a grainy structure to the crumb.
- Wheat flour
- Gives the batter structure so the cake holds its shape after steaming.
- Baking soda
- Reacts with the sour milk to produce gas that lightens the batter.
- Molasses
- Adds sweetness, moisture and deep colour to the cake.
- Sour milk
- Supplies acidity that activates the baking soda and tenderises the crumb.
The step that matters
Steam with the steamer tightly covered. Steam is the only heat source for the batter, so any escape lets the steam drop and the cake can turn out dense and wet. Keeping the water boiling and the lid sealed maintains steady heat for the full steaming time.
