I dunno what I am doing wrong but I have tried the OP's recipe 3 times, 2 twice at home and once in camp and each time resulted is an inedible bannok fit for the trash along with unused mix.
There is an awful bitter metallic after taste which burns to the degree that the tasters (not just me) pallet was left stripped. I assume this is due to the stated quantity of baking powder used, as said I do not know what else I am doing wrong.
Reading on this thread that others have cooked via this recipe and posted their findings as a tasty bannock really irks me
... are they heavy smokers with no sense of taste?
Having experimented with the original recipe and taking advice on recommend baking powder quantities I have come to a recipe I am happy with which produces something tasty and edible for me (Although I am still playing with quantities). As long as the dough is not kneaded to death the quantities I have stated produce 4 of 8inch diameter by a risen 1.25 inch thick cooked bannocks, one of which is more than enough for a mans meal.
12 oz (cup n half) self raising flour
12 oz (cup n half) wholemeal plain flour
4 oz (half cup) dried skimmed milk
4 oz (half cup) vegetable suet
2 tablespoon baking powder
1/2 teaspoon salt
1 heaped teaspoon unrefined sugar
Optional: Add 2 oz of dried fruit, nut or seeds to the mix. My current favourite is palmful of torn dates and sunflower seeds.
