I've learned a lot about frontier foods, and American cookery in general, from this book. I was surprised to discover that the "biscuits" referred to in the Little House books are actually what English people would call a dinner roll! Over here, a biscuit is a hard object, such as Americans might call a cookie, or maybe a cracker?
However, it's not always easy to transpose the recipes for an English kitchen. The amounts are in American measures, which is not insurmountable, but it is impossible to buy salt pork, or some of the other supplies, over here, and I also have no idea how to translate "homogenized milk", "lima" or "navy" beans into UK English. If any American readers know the answer to this, please leave a comment and enlighten me!
