Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Oat Cakes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, cream together the butter and lard mixture with the sugar.
Add the salt and mix well.
Dissolve the baking soda in the buttermilk and add it to the mixture.
Stir in the rolled oats, then gradually add the flour.
Bake
Drop spoonfuls of the mixture onto a baking sheet and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rolled oats
- Provide chewy texture and a toasty, nutty flavour in the finished cookies.
- All-purpose flour
- Gives the dough structure so the spoonfuls set rather than spread too far.
- Butter and lard mixture
- Adds fat for richness and tenderness, and helps the cookies brown.
- Sugar
- Sweetens the dough and helps create golden browning in the oven.
- Baking soda
- Reacts with the acidic buttermilk to release gas, helping the oatcakes rise and spread.
- Buttermilk
- Adds moisture and acidity that activates the baking soda for lift.
The step that matters
Dissolving the baking soda in the buttermilk. Baking soda needs an acid to react and produce carbon dioxide. Dissolving it fully in the buttermilk spreads it evenly through the dough, so the oatcakes rise uniformly instead of having pockets of bitter, unreacted soda.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
