Cut vegetables as desired, then tightly pack into 2 or 3 pint-size (2-cup) mason jars. (If using beets, give them their own jar.) Combine vinegar, water, sugar, salt, dill (or fennel fronds), coriander and mustard seeds and peppercorns in a medium saucepan. Bring to a simmer over medium-high heat, about 4 minutes. Pour the brine over the vegetables. Let cool to room temperature, about 1 hour. Refrigerate for at least 24 hours before serving.Advertisement
To make ahead: Refrigerate for up to 3 weeks.
