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. 
Yes, and unlike the canning process, you dont have to completely sterilize foods before they're pickled.
