In Scotland (and other parts of the British Isles) when making "mince and tatties" (cooked ground beef accompanied with boiled potatoes) it's not uncommon to cook doughballs, or dumplings in the mince near the end of the cooking process.
Normally I'd do this with self-raising white flour, shredded suet (using a product branded as Atora), water and a pinch of salt. However due to supply chain problems these days all I could get was strong brown flour and suet. What do I need to add to the mix that would give me the "self-raising" action? I'm thinking baking powder, but I don't know how much to add per 100g of brown flour to create "self-raising brown flour".
Any guidance would be appreciated.
