I was thinking of getting into pickling. Are you familiar with the process?
Yeah, that's where you immerse food in vinegar, or brine to preserve it's lifespan. 
Pickling seems like it isnt too expensive to get into either. What kinds of foods can I pickle?
A variety of food items like meats, fruits, eggs, and vegetables can be pickled.
Oh really? Can you tell me more about the process of pickling?
If you do it right it can kill most bacteria.
I see. Im guessing pickling was more common before modern refrigeration.
pickles are made by placing vegetables in vinegar. Like the canning process, pickling (which includes fermentation) does not require that the food be completely sterile before it is sealed. The acidity or salinity of the solution, the temperature of fermentation, and the exclusion of oxygen determine which microorganisms dominate, and determine the flavor of the end product.
When both salt concentration and temperature are low, "Leuconostoc mesenteroides" dominates, producing a mix of acids, alcohol, and aroma compounds. At higher temperatures "Lactobacillus plantarum
Pickling
Pickling is the process of preserving or extending the lifespan of food by either anaerobic fermentation in brine or immersion in vinegar. In East Asia, vinaigrette (vegetable oil and vinegar) is also used as a pickling medium. The pickling procedure typically affects the food's texture, taste and flavor. The resulting food is called a "pickle", or, to prevent ambiguity, prefaced with "pickled". Foods that are pickled include vegetables, fruits, meats, fish, dairy and eggs.
