Step 1

Heat the oven to 375 degrees. Peel the beets and cut into 1-inch chunks. Toss with the oil and season with 1/4 teaspoon salt and pepper. Roast for 30 minutes, tossing occasionally, then sprinkle with mustard seeds, coriander and cumin and roast until the beets are tender, about 15 minutes more.

Step 2

While the beets roast, prepare the dressing: using the side of a knife or mortar and pestle, mash the garlic with a pinch of salt until it forms a paste. Place yogurt in a bowl; whisk in garlic paste, jalapeño, ginger, 1/4 teaspoon salt and lime juice. Whisk in the cilantro.

Step 3

Scrape the warm beets into a large bowl. Stir in the dressing and pomegranate seeds, if using. Taste and adjust seasonings if necessary.
