Finally getting round to having a go at Fandabi Bannocks, a survival ration biscuit thing which, whilst not traditional, was very doable in the 1700s or whenever. Just a few ingredients: suet, oats, wheat flour and salt. I've added dried fruit too, but no sugar. Ultimate aim is to test the shelf life, I'm going to store them in cool, dry, but not refrigerated conditions, and take bacterial swabs ever 6 months or so from the surface and inside, see what I can grow. https://www.youtube.com/watch?v=V0cxV2vVC0U
