Yield: 5 pints
~12 medium sized beets (ideally, your beets are the same diameter as your jars)
1 cup water
1 cup white vinegar
1 cup sugar
Wash beets well. Trim roots, but leave attached to vegetable so the beet doesn't bleed too much when cooked.
Put beets in boiling water for 30-45 minutes (until they peel easily).
Peel beets. Put in cold water to cool.
While beets are cooling, mix water, vinegar, and sugar. Warm on stovetop until hot, but not boiling.
Meanwhile, warm jars and lids. Use mandolin to slice beets ~1/8-1/4" thick.
