Introduction to Grandma’s giardiniera
The sweet-and-sour giardiniera is one of the Grandma’s recipes that I love, usually made at the end of summer when there is still a bit of this and that in the garden. That’s exactly what I did this year… I gathered zucchini (large), eggplants, bell peppers, carrots, green beans, pearl onions and finally cabbage. The giardiniera I obtained is a specialty; I recommend everyone try it and put away a true delicacy for the winter.
Note: This “Giallo Zafferano sweet-and-sour giardiniera” recipe is the original Grandma’s version, the traditional one: crunchy vegetables, balanced flavor and a simple method.

Green beans: trim the ends and wash them.
Pearl onions: remove the outer skin.
Red bell peppers: wash, halve, remove seeds and membranes, then cut into large pieces.
Cabbage: cut into 4 wedges, slice each wedge, immerse in cold water and wash.Sterilization: Before starting to cook the vegetables, sterilize 24 jars of about 17.6 oz (500 g) each.
Preparing the jars: Once ready, place them on the work surface so you can fill them quickly with the hot vegetables.Start: In a large pot pour in 8 1/3 cups of vinegar, 8 1/3 cups of wine, 3 1/3 cups of oil, 1 1/2 cups of salt and 2 cups of sugar.
Heating: Put the pot on the stove and heat until it reaches a boil.
Hard vegetables: When the liquid boils, add the hardest vegetables first and cook them for about 2 minutes.
Softer vegetables: Then add the softer vegetables and continue cooking for another 3 minutes, for a total of 5 minutes.Filling: After 5 minutes turn off the heat and immediately start filling one jar at a time with the vegetables, pressing them slightly with the back of a spoon.
Top up: Fill each jar by pouring the hot liquid up to the brim, then close it well and immediately invert it to create the vacuum.
Procedure: Continue in the same way for all the jars, working quickly.
Cooling: Once all jars are filled, leave them inverted until completely cool.
Storage: Finally transfer them to a cool, dark place.
Storage: sweet-and-sour giardiniera
Long-term storage: Sweet-and-sour giardiniera keeps for the whole winter.
After opening: Once opened, if you don’t consume all the giardiniera, store it in the refrigerator where it will keep for about 3 days.
Adjusting quantities: The amount of vegetables can be increased or decreased according to your preferences; in that case you must also adapt the doses of the other cooking ingredients.
🌿 Variation: Grandma’s giardiniera preserved in oil
If you want a more traditional version that keeps for a long time, you can turn the giardiniera into giardiniera preserved in oil: drain the vegetables well from the pickling solution, let them dry for 6–12 hours, arrange them in jars and cover them with plenty of extra virgin olive oil, eliminating air. Rest 7–10 days before consuming.

Useful questions about sweet-and-sour giardiniera
Can I change the vegetables without risking the vacuum seal?
Of course! I often replace or add vegetables as I like. The important thing is to respect the proportions of liquid, salt and sugar so the vacuum seal is perfect.
How do I keep the vegetables nice and crunchy?
Here’s a trick: cook everything for only 5 minutes and fill the jars immediately with the boiling liquid. This way they stay crunchy and colorful.
How do I get a perfect vacuum seal?
Just fill the jars with hot vegetables, pour the liquid to the brim, close well and immediately invert the jar until it cools completely.
Can I give the giardiniera an extra touch?
Absolutely! Sometimes I add bay leaves, whole peppercorns or a little garlic: the result is a more intense and aromatic flavor.
How can I tell if the vacuum seal worked?
After cooling, the lid should be slightly concave. If you press it and it doesn’t “click”, you’re fine.
Can I prepare it in advance and give it as a gift?
Yes! I have often made it for friends and family. Just check that the jars are well sealed and store them in a cool, dark place: they will be snapped up.
How long can I store Grandma’s giardiniera?
Grandma’s sweet-and-sour giardiniera keeps up to 1 year if the jars are well sealed and stored in a cool, dark place. If you wish, you can also pasteurize the jars by immersing them in boiling water for 20–25 minutes: this way they remain safe and ready to be gifted, without altering their flavor.
