Makes 2 quarts
(recipe adapted from MyRecipes.com )
Combine first 5 ingredients in a medium saucepan. Bring to a boil, reduce heat, and simmer 3 minutes. Put all of the chopped cauliflower, peppers, onions & carrots in a large bowl. Mix to combine and then divide mixture between two quart sized-mason jars. Top each jar with half the dried herbs, peppercorns, Serrano peppers and garlic. Carefully pour vinegar mixture over cauliflower mixture. Place the lids on the jars and slightly agitate to evenly mix. Take the lids off the jars and let giardiniera cool off, about 15 minutes. When cool, seal the jars tightly and place in the refrigerator for at least 2 days, making sure to agitate a couple times per day. The giardiniera will last for up to a month in the fridge.
-If your vinegar mixture doesn't fill up the jars all the way, don't fret! Add a bit of water! Agitate it. Done.
