Wash the carrots thoroughly, peel, and slice them thinly.
Place the sliced carrots in a glass jar.
Make the pickling brine by mixing vinegar, water, salt, and stevia or erythritol.
Bring the pickling brine to a boil, then pour it hot over the carrots.
After it cools completely, cover it with a lid and let it marinate in the refrigerator for at least a day.
