Homemade pickled beets - a tasty and easy-to-make side to have on-hand

I made homemade pickled beets for the first time. It was easy: wash, peel, boil, slice, and marinate in a simple brine (vinegar, water, garlic cloves, peppercorns, salt, etc.). A wide-mouthed mason jar is ideal. And then you have a tasty homemade side/ garnish/ pickle on-hand that you can add to any meal. Yum! Would recommend. I feel there's a lot of margin for error on this recipe, and also that I could improve my brine game over time :P. The one warning: be careful of beet juice stains! Don't let beet juice sit on something stainable if you don't want it to stain!
