Product Overview
Turnips are a widely cultivated root vegetable valued for their mild flavor, versatility, and dual-purpose use of both roots and leafy greens. They are an important commodity in fresh produce markets, serving retail and food service sectors. Turnips are consumed both raw and cooked and are commonly used in a variety of traditional and modern dishes.
Key Characteristics
Turnips are round to slightly flattened roots with smooth skin that is typically white with a purple or green top depending on sun exposure. The flesh is firm, crisp, and white with a mildly sweet and slightly peppery flavor. Texture becomes softer and sweeter when cooked. Turnips are non-climacteric and do not ripen after harvest.
