Makes 1 qt. jar
Preheat oven to 400°. Rinse and dry the beets, place in a piece of foil and drizzle with oil. Wrap up and place on a baking sheet. Cook for 30 min. to an hour depending on the size of the beets, or until you can easily pierce them with a paring knife. * Steamed and peeled beets are available usually at Trader Joe’s or always at Melissas.com
Put mustard seeds into the bottom of the jar and add an orange.
Let the beets cool after roasting until you can handle them in your hand. Rub the skin off the beets with a paper towel, remove root and cut the top off.
You can cut the beets however you like, into wedges, slices or half slices, then place into the jar.
Place the vinegar, water, and salt in a large measuring cup or bowl and stir to dissolve the salt. Pour over the beets, leaving a 1/2” space at the top. Slide a table knife down the side of the beets to release any trapped air. Refrigerate for 24 to 48 hours
Storage: Since these beets are not canned, they must be stored in the refrigerator. Refrigerate pickled beets for up to 2 months, but if any off flavors or aromas develop or if fermentation begins, it is best to discard the remaining beets.
