Ingredients & Diet
The daily diet for most people in Iron Age Britain was a combination of bread, porridges and stews. Wheat and barley were two of the most common crops grown by Iron Age people. They would have been ground into flour to make bread, using quern stones. Barley and wheat could also be used in porridges and stews. Celtic beans and Fat Hen (small succulent flowering plants ) were also a common part of the diet along with early types of brassicas (probably parsnip). Milk from cows and possibly sheep was available at some times of the year and was probably used to make cheeses.
