I recently found my deceased mum’s handwritten cake recipe book and want to bake her gingerbread cake, but there’s an ingredient I can’t work out. It’s the last in the list of ingredients:
1 tbsp b.w.
What on earth might b.w. stand for? Does anyone have an idea? I’m trying to make in into baking soda/baking powder - which seems more likely for a gingerbread cake? I’m not an experienced baker! Help please!
