Add half the beet juice to the blender, then the frozen berries and tahini. Pulse until as smooth as possible, scraping every so often. Add the rest of the beet juice and blend until smooth, adding more liquid as needed.
Emma is the food editor at Food52. Before this, she worked a lot of odd jobs, all at the same time. Think: stir-frying noodles on the fly, baking dozens of pastries at 3 a.m., and writing about the history of pie in North Carolina. Now she lives in New Jersey with her husband and their cat, Butter. Stay tuned every Tuesday for Emma's award-winning column, Big Little Recipes (also the cookbook in November 2021!). And see what she's up to on Instagram at @emmalaperruque.
