Ingredients

Method

Place 6 small carrots (about 8 oz.), peeled, sliced on a diagonal, and 1 tsp. crushed red pepper flakes in a 2-cup heatproof container. Place 1 medium fennel bulb, trimmed, thinly sliced, and 1 tsp. ground turmeric in another 2-cup heatproof container and 1 medium red onion, sliced ½" thick, in a third container.

Bring 2 cups distilled white vinegar, ½ cup (100 g) sugar, 2 Tbsp. Diamond Crystal or 1 Tbsp. plus ½ tsp. Morton kosher salt, and 2 cups water to a boil in a medium saucepan over medium-high, stirring until sugar and salt are dissolved.

Pour brine evenly among containers with vegetables and let cool. Cover and chill at least 12 hours and up to 4 days.
