Wash the vegetables. Clean the bell peppers of seeds and cut them coarsely. Peel the carrots and cut them into round slices, tear the cauliflower into small rosettes, cut the celery leaves coarsely.
Remove from the stove, add the aspirin ground to powder and let it cool. Put the vegetables in 2 jars of 12 1/2 cups (3 L) each and 1 jar of 4 1/5 cups (1 L), while pressing them lightly.
Pour in brine up to the rim and close with caps. If you need just a little more, top off with water and a little salt. Store the jars in a dark and cool place.
