The original recipe calls for only radishes, but I decided to do both cucumbers and radishes. You only need to make this about 20-30 minutes ahead of time. Leftovers should be eaten within a couple of days of making it. For some reason marinated radishes get truly stinky after more than that. A mandolin works great for slicing.
About 8-10 radishes, thinly sliced
1/2 English cucumber, UNPEELED and thinly sliced
3 cloves of garlic, peeled and smashed
1/2 c. rice vinegar
1/2 c. water
2 T. sugar
2 t. salt
1 t. white pepper
Recipe
Mix together the rice vinegar, water, sugar, salt, and white pepper in a lidded bowl or jar big enough to hold all of the ingredients. Add the radishes, cucumbers and garlic. Cover and refrigerate at least 20 minutes.
