Wash the radish and peel its skin.

Slice the radish thinly into rounds. If preferred, cut slightly thicker for a crunchier texture.

Combine 1.5 cups vinegar, 1 cup sugar, and 1 tbsp salt in a bowl.

Add the sliced radish to the mixture and toss well.

Let the radish sit, occasionally stirring to help the flavors blend and sugar dissolve.
