Visual Characteristics of a Head of Radicchio
Understanding what a head of radicchio looks like can enhance your grocery shopping experience and culinary endeavors. Here, we explore its key visual attributes in detail.
Shape and Size
A head of radicchio typically resembles a small, compact cabbage or a large, round lettuce.
- Size: On average, a radicchio head is about 6 to 8 inches in diameter.

This contrast not only makes radicchio visually appealing but also prepares your palate for the robust flavor that awaits.
