Step 1

Toss the zucchini, onion, shallots, and salt together in a colander and place over a bowl to catch the liquids. Cover the bowl and refrigerate for at least a couple hours. Toss once or twice along the way. You're aiming to get as much liquid out of the zucchini as possible.

When you're finished draining the zucchini, shake off any water. At this point you want the zucchini as dry as possible. Place in a 1 liter / 1 quart jar along with the dill, chile pepper, and mustard seeds. Alternately, you can cram them into a 3/4 liter Weck jar like I do, but it's always a bit snug in the jar.

Step 2

Combine the ciders and sugar in a small saucepan over medium heat. Bring to a simmer, stirring until the sugar dissolves, and continue to boil for a few minutes. Pour the liquid over the zucchini and seal the jar. Let cool, then refrigerate. The pickles are good for a week or so.
