17. Food Preservation
Food preservation used to be essential because what you ate had to be in season and if you wanted to safely store food, than you had to know how to preserve it or risk getting poisoned. Storing food for the Winter used to be a priority for everyone; food preservation methods can be traced back to ancient times and were commonly until your grandparents era. Food preservation methods that don’t include the modern day refrigerator and freezer are: canning, smoking, curing, salting, pickling, and drying. It might be a good thing that the common person doesn’t preserve food at home because popular methods like salting and smoking can actually hurt your health if consumed in large amounts. However, pickling and canning can easily be done at home and there are many how-to guides on the internet.
