Scrub the beets thoroughly and trim off the greens, leaving only the bulbs.
Place the beets in a baking dish and toss them with olive oil, ensuring they are evenly coated. Season the beets well with salt and black pepper.
Pour water into the baking dish until the beets are almost covered and cover it tightly with foil.
Roast the beets in the preheated oven for approximately 45-60 minutes or until they are tender. You can check for doneness by inserting a fork or knife into the beets; it should go in easily when they are ready.
Once roasted, allow the beets to cool slightly before handling. Peel off the skin using a paper towel or your fingers (wear gloves to prevent staining).
Preparing the Brine:
In a saucepan, combine apple cider vinegar, rice wine vinegar, and sugar.
Place the saucepan over medium heat and stir until the sugar is completely dissolved.
While the sugar is dissolving, create a sachet with a cheesecloth. Combine kosher salt, yellow mustard seed, celery seed, black peppercorn, red pepper flake, dry dill, and fennel seed. Tie the spices securely in the cheesecloth to make a sachet.
Once the sugar is dissolved, add the spice sachet to the vinegar mixture.
Allow the brine to simmer over medium heat for about 10-15 minutes, infusing the liquid with the flavors from the spice sachet.
Remove the spice sachet from the brine, ensuring that the flavors are infused without any loose spices.
Pickling the Beets:
Slice the roasted and peeled beets into your desired thickness. Place the beet slices in a clean, sterilized jar or container.
Pour the warm brine over the beets, ensuring they are fully submerged.
Allow the pickled beets to cool to room temperature before sealing the jar or container.
Once cooled, refrigerate the pickled beets for at least 24 hours to enhance the flavors.
