What each ingredient does

Split or bruised peas
Supply the starch and natural microbes that ferment the mixture and produce the froth.

The step that matters

Keeping the mixture warm for 24 hours. Fermentation by wild yeasts and bacteria runs faster and more reliably at warm temperatures. In a cool spot it may be slow or fail to froth, so the mixture should be kept in a warm place as the step directs.
