1 bunch of radishes
red wine vinegar
pinch of salt
Slice radishes and place in mason jar. Fill half way with cold water, and fill the rest of the jar with red wine vinegar. Add a pinch of salt.
Close lid and shake.
For a spicy treat, add chili flakes to the vinegar mixture.
The radishes will last a long time in the fridge since they are stored in vinegar. You can also add sliced onions, or turnips to the jar.
It usually just takes a few hours for it to marinate. You'll be able to tell when they're ready to eat as they'll turn into a pretty shade of pink.
