Heres a list of some stuff I have used in bannock/pancakes:
Walnut Oil. (use it instead of margarine, or fry pancakes in a little oil).
Ground Almonds. (just add a spoonful when mixing dry ingredients).
Pistachio nuts. (or any other nuts you fancy. These need to be bashed up small, and don't add too many, or they stop the dough from rising).
Dried Fruit. (any kind you fancy. soak it in a plastic bottle for a couple of hours, drain it and chop it up small).
Olives. (chopped up small).
Sun Dried Tomatoes. (same as above).
Herbs. (either freshly picked, or dried. Only use less than a Teaspoonfull).
Cheese. ("Stinkier" the better, Parmesan, Stilton, Goat cheese. Either add a small amount to the dough, or stick it on the top, like cheese on toast).
Bacon/Salami. (chopped up small).
Now......Wheres my frying pan gone?
