A Root Vegetable’s Rich History
The radish boasts a fascinating history, stretching back thousands of years. Its origins are believed to be in Southeast Asia, with evidence suggesting radishes were cultivated as early as 2700 BC in ancient Egypt. From there, these crisp, colorful roots spread throughout the ancient world, finding favor in Greece, Rome, and beyond. Early varieties were often larger and more robust than those commonly found today, resembling parsnips or turnips. The Romans, in particular, cultivated and enjoyed radishes and were even mentioned in agricultural writings. In China and Japan, radishes also played a significant role in traditional diets and medicines, with daikon radishes becoming a staple in East Asian cuisine.

Ingredient Preparation: Mastering the Radish
Proper preparation is key to enjoying radishes to their fullest.
- Cutting Radishes:
- Wash radishes thoroughly.
- Trim off the green tops and the root end.
- Slice, dice, quarter, or leave whole, depending on your recipe.

- Mincing Radishes:
- Less common, but for a finer texture, you can use a grater or a food processor, remembering it will impact the wonderful crisp texture.
Storage: Keeping Your Radishes Fresh
Proper storage is crucial to maintain the crispness and flavor of radishes.
- Short-Term Storage:
- Trim off the green tops to prevent moisture loss.
- Store unwashed radishes in a plastic bag or container in the vegetable crisper drawer.
- Long-Term Storage:
- Place radishes in a container with cold water, changing the water every day. This can extend their shelf life for a week or two.
- Shelf Life: Properly stored radishes in the fridge should last for 1-2 weeks. When stored in water, they may last slightly longer.
