What is a watermelon radish and how does it differ from other radishes?
The watermelon radish, also known as the “美乐” or “xīng luó” in Chinese, is a type of radish that belongs to the family Brassicaceae.

Can you eat the outside of a watermelon radish, or should it be peeled before consumption?
The outside of a watermelon radish, also known as the skin, is technically edible and can be consumed without peeling. However, the skin may be slightly tougher and more bitter than the flesh, which can affect the overall texture and flavor of the dish. In some recipes, the skin is left on to add color and texture, while in others, it is peeled to reveal the sweeter and milder flesh. If you choose to eat the skin, make sure to wash the radish thoroughly to remove any dirt, bacteria, or other contaminants.
When deciding whether to peel or not to peel the watermelon radish, consider the desired texture and flavor of your dish. If you’re looking for a more delicate flavor and a smoother texture, peeling the radish may be the better option. On the other hand, if you want to add a bit of crunch and color to your dish, leaving the skin on can be a great way to do so. Ultimately, the choice to eat the outside of a watermelon radish depends on personal preference and the specific recipe you’re using. By understanding the unique characteristics of the watermelon radish, you can make informed decisions about how to prepare and enjoy this versatile root vegetable.
