Heat some butter in a pan until foaming. If you want the outside golden and with the slight saltiness you must use butter, it’s just not the same with oil. I do add a little oil to stop the butter burning but not much. These little cakes like to soak the butter up so have some spare to dot around the pan. Place the cakes in the pan, you may have to do more than one batch, and wait until they are golden until you turn them over. Turn them too early and you might end up with a right mess.
