- Melt the butter in a pot over a low heat. Stir in the flour, rapadura (sugar), and flavours (cocoa, ginger, spices), and add a slurp of Herman and any other liquids, put on the lid and leave the mixture at room temperature for a few hours (you can start this in the morning and bake in the afternoon, or even put it all in the fridge after a few hours and bake it later the next day, just depends on the outside temperature, in winter you could probably leave it out overnight).
- When you're ready to bake, add the egg and a good heaped tablespoon of baking soda (leave out the baking powder). The baking soda is enough to rise the batter because the fermentation has made the batter acidic and the baking soda is alkaline, when the two mix, they produce carbon dioxide (and water and a salt) which rises the batter (baking powder contains both baking soda and citric acid, and works in the same way, if you add baking powder to water you will see it bubble as the carbon dioxide is released).
