Ingredients

Method

Place beets and radishes in a small bowl. Toast fennel seeds in a dry small saucepan over medium heat, shaking pan often, until fragrant, about 45 seconds. Add vinegar, salt, sugar, and ½ cup water and bring to a boil, stirring until salt and sugar are dissolved, about 1 minute. Pour brine over beets and radishes and let cool. Cover and chill at least 8 hours before serving.

Do Ahead: Vegetables can be pickled 1 week ahead. Keep chilled.
