Visual and Textural Differences
Though both escarole and kale are leafy greens, their visual and textural differences are significant. Understanding these differences can help you determine which one to use based on your dish.
- Escarole: Pale green with broad, tender leaves. Its texture is softer and wilts quickly when cooked. It has a mild bitterness, which makes it versatile in both raw and cooked dishes.
- Kale: Dark green, with curlier and sturdier leaves. Kale maintains its firm texture even after long cooking processes, making it ideal for dishes that require more structure, like stews and roasted dishes.
The visual difference is striking when they are side by side. Escarole looks more like lettuce, while kale has a firmer, more rugged appearance. This makes kale better suited for dishes where you want the leaves to remain intact.
