Divide garlic, peppercorns, mustard seeds, coriander seeds, dill, and red pepper flakes (if using) evenly between two jars. Fill to top with cauliflower florets.

Notes
Storage: Makes 2 quarts. Cauliflower pickles will keep in the fridge for 3-4 weeks. The flavor will intensify with time.
Adding Additional Vegetables: If desired, add other veggies. Cauliflower and carrots make a nice color combo but you could add other crisp vegetables, too, such as sliced onions, green beans, or celery. Experiment and see what you like best.
Yellow Cauliflower: If desired, add a 1/2 teaspoon of ground turmeric for a bright yellow color.
Sweetness: You can increase the sugar for a sweet pickle, or make the pickles without sugar. A little sugar does temper the acidity of the vinegar but it's technically optional.
Vinegar: Other types of vinegar that will work: Apple cider vinegar or rice vinegar. We do not recommend using balsamic or malt vinegars.
