Chicago-Style Italian Giardiniera
Giardiniera (jar din yair) means roughly "from the garden", an Italian American condiment made from fresh vegetables. Because it is chopped into small bits and used to top sandwiches and other foods, technically it is a relish, but it is not at all like a sweet pickle relish.
There is no single recipe for giardiniera. The exact ingredients and method vary from bottler to bottler, and it can be made from mild to hot with infinite grades in between. At its core, giardinera is a blend of garden vegetables.
In Chicago giardinera is extremely popular and can be found in all the hundreds of restaurants that serve Italian Beef Sandwiches and Italian Sausage Sandwiches where it is practically a required topping. A jar of giardiniera can be found in the door of every Italian American fridge in Chicago.
In New Orleans it is used to top muffuletta sandwiches and on nachos at sports stadia. It can also be used on meatball sandwiches, mortadella, bologna, and practically any other sandwich. Some folks serve it straight with antipasto, straight as a salad, on a salad, in soups or in sauces. Rachael Ray puts it on pasta, and I know of people who use it on scrambled eggs.
Below is my recipe, heavily influenced by a different recipe taught to me by my sister-in-law Theresa Tortorello of Destination Vacation travel (she is expert on travel to Italy and Hawaii among other destinations). She is an accomplished Italian American home cook who learned her recipes at the aprons of her immigrant family. She makes a large quantity of giardiniera in August using the bounty of her garden.
The most popular commercial brand, Dell'Alpe is simply serrano peppers, green olives, celery, and spices. Pretty simple and boring. But Theresa and I like more stuff in it. You can increase or decrease ingredients to your taste. If you can't find fennel bulbs, skip them. Want more garlic, go for it. I recommend you start with this recipe and then, after aging it a few days, you can add more ingredients if you wish.
Some commercial bottlings are packed in oil only. You should not make it this way because botulism bacteria love that environment. My recipe uses vinegar to make sure it is low enough in pH (acidic) to discourage microbial growth. It can be stored in the fridge for several weeks. Giardinera can also be sterile canned if you know how. For more info on sterile canning go to the Ball jar company website FreshPreserving.com.

About the hot peppers. If you want more hot chiles, go easy at first. You can always add more after you taste the mix. Use cayennes, jalapeños, or serranos. If you have an asbestos mouth, add some habaneros. If you don't want a lot of heat, remove the veins from the inside, that's where the heat hides. And wear gloves when handling them. Here's a good strategy: Buy an extra hot pepper or two. Make the recipe and if it's not hot enough after a day or three, andd more. Click here to read more about chiles and other peppers.
About the sweet peppers. Use a variety of sweet bell peppers, green, red, yellow, and orange. In Chicago the traditional recipe also calls for using some Melrose peppers, a long thin walled green pepper that is not hot at all. Melrose are hard to find so you can substitute any mild pepper, like banana peppers. Or just stick with the bells.
About the zucchini. If there are large seeds, scoop them out. The yellow squash is a bit firmer and crunchier.
About the basil and oregano. As a garden recipe, this calls for fresh herbs, but you can use dried. If you use dried, use 1/3 the quantity since dried is more concentrated. Click here to learn more about herbs and substitutions.
About the oil. You can use olive oil, but it will solidify and get cloudy when chilled. As soon as it warms to room temp it will clarify and flow. Canola oil will remain liquid in the fridge, but you can use corn oil or a salad oil blend.
About the olives. You have a lot of flexibility here. You can use kalamata olives or canned olives, green or black, packed in oil or brine, or all of them. Just be sure to get pitted olives.
1) Make sure all the vegetables are thoroughly washed. Chop and dice them.
2) In a bowl, mix the veggies. In another bowl, whisk together the dressing ingredients.
3) Spoon the veggies into a very clean jar and top them off with the liquid. Make sure the solids are covered in liquid and use a kitchen knife to dislodge large bubbles. If you need it, pour in more oil and vinegar, about 2 parts oil to 1 part vinegar. Screw on a tight fitting very clean lid and refrigerate. You can use it immediately, but you should give it at least three days to allow the juices from the veggies to come out and the flavors to marry. Then shake and taste and make additions as you see fit. It will keep for weeks in the fridge. If you know how to sterile can, you can put a batch up for use all winter.
