Pickled zucchini – ingredients and equipment

Ingredients
| Ingredient | Grams | Percent |
|---|---|---|
| apple cider vinegar | 750 ml | |
| sugar | 400 g | |
| water | 250 ml | |
| zucchini | 5 piece | |
| shallots | 4 piece | |
| salt | 2 tbsp | |
| yellow mustard seeds | 1 tbsp | |

Equipment
Preserving jars
You’ll need 3 clean preserving jars with screw-top or clip-top lids, about 500 ml each. Sterilize them with boiling water first so the zucchini keeps well. I prefer Mason jars, but traditional preserving jars work just as well.
Pickled zucchini – step-by-step instructions
Wash and slice the zucchini
Wash the zucchini thoroughly, dry them and cut into even slices about 5 mm thick. Even slices help every piece absorb the pickling liquid equally.
Slice the shallots
Peel the shallots and slice them thinly. They give the pickling liquid a mild, slightly sweet flavor.
Boil the pickling liquid
Mix the apple cider vinegar, water, sugar and spices (mustard seeds, turmeric and celery seeds) in a saucepan. Stir well and bring to a boil. Simmer gently for 5-10 minutes to develop the spices’ flavors.
Dry the vegetables
Drain the liquid released by the vegetables. Squeeze the zucchini well and pat dry with a kitchen towel. Remove as much water as you can. You don’t need to rinse off the salt: it drains away with the water, and what’s left suits the pickling liquid perfectly.
Fill the jars and add the liquid
Put the zucchini in sterilized jars. Press down with a spoon to leave as little air as possible. Leave a finger’s width of space at the top. Carefully pour the hot liquid over the vegetables until they’re completely covered. Press down again with the spoon to release air bubbles.
Cool and let the flavors develop
Let the jars cool uncovered, then seal tightly. Refrigerate for at least one day. The longer the zucchini infuse, the more intense the flavor. After a week, they’re perfectly infused.
Your pickled zucchini are ready. Enjoy!

Mixed zucchini pickles
A little variety is always good. Use my basic recipe and replace about 30 % of the zucchini with bell peppers. They add gentle sweetness and look lovely in the jar.
