What Are Sugar Roasted Radishes with Butter and Sea Salt?

Sugar roasted radishes with butter and sea salt are a simple yet sophisticated side dish that highlights the natural sweetness of radishes. By roasting them in the oven, their sharp, peppery flavor softens, revealing a mellow, almost caramelized taste. A touch of sugar enhances this transformation, while butter adds richness and sea salt provides the perfect finishing balance.
