What each ingredient does

Sour milk or buttermilk
Acidifies the batter so the baking soda can react and lift it.
Oat meal
Forms the bulk of the batter and gives the gems their hearty, tender body.
Baking soda
Reacts with the acidic milk to produce gas that makes the gems rise and lighten.

The step that matters

Dissolving the baking soda before stirring it in. Baking soda needs to be evenly dispersed in the batter to react with the acid in the milk. Dissolving it in a little water first helps it spread evenly, so the gems rise uniformly rather than in patches.
