Preparations

How to actually make the things, and why each method works the way it does. The chemistry is not decoration: it explains why aromatic herbs are dried in the shade and not in an oven, why roots have to be sliced before drying, why fermentation raises the minerals a body absorbs from grain, and why covering fresh garlic in oil and leaving it sealed is a botulism risk and not a preservation method. Where a method has a safety line, the line is drawn where the evidence puts it.
