This is one of those tasty treats you can get in Chicago, but it's hard to find elsewhere. A few years ago I found a recipe in the paper and we've made it a few times - the homemade version is even better than the jars you can get at the store. It is great on sandwiches or nachos.
Preparation time: 1 hour
Chilling time: 2 1/2 days
Yield: 3 cups
6 jalapenos, thinly sliced (I usually only do 3 so it's not too spicy)
2 each, diced: green and red bell peppers
1 each, diced: celery rib, carrot, yellow onion
1/2 head cauliflower, cut into florets
1/2 cup salt
3 cloves garlic, minced
1/2 cup chopped stuffed green olives (I usually omit)
2 1/2 teaspoons dried oregano
1/2 to 1 teaspoon red pepper flakes
1/2 teaspoon celery seeds
Freshly ground black pepper
1 cup each: apple cider vinegar, extra-virgin olive oil
1. Combine the jalapenos, bell peppers, celery, carrot, onion and cauliflower florets in a large bowl; stir in the salt. Add cold water to cover vegetables; cover bowl. Refrigerate 12 hours. Drain salt water; rinse vegetables. Set aside in the bowl.
2. Combine the garlic, olives, oregano, red pepper flakes, celery seeds and black pepper to taste in a medium bowl; set aside.
3. Pour the vinegar into a medium bowl; whisk in the seasonings. Whisk in the olive oil. Pour over the vegetable mixture; toss lightly. Cover;refrigerate at least 48 hours before using. The giardiniera will keep in the refrigerator for several weeks.
