Common Types of Kale and Their Characteristics
Curly Kale
Curly kale is perhaps the most recognizable and widely available type of kale. It features tightly ruffled leaves with a bright green color and a somewhat bitter, peppery flavor. This variety is known for its robust texture, which holds up well in cooking.
Nutritionally, curly kale is a powerhouse. It's particularly high in vitamins A, C, and K, as well as antioxidants like beta-carotene and lutein. The sturdy leaves of curly kale make it an excellent choice for kale chips, sautés, and hearty soups.
Lacinato Kale (Dinosaur Kale)
Also known as Tuscan kale or dinosaur kale due to its bumpy, reptilian-like texture, Lacinato kale has long, narrow leaves with a dark blue-green color. It has a slightly sweeter and more delicate flavor compared to curly kale, with a tender texture that becomes even silkier when cooked.
Lacinato kale is rich in vitamins A and C, as well as manganese and calcium. Its tender leaves make it an excellent choice for raw salads, pesto, and quick sautés. Many people find its milder flavor more appealing, making it a great introductory kale for those new to this leafy green.
Red Russian Kale
Red Russian kale stands out with its purple-red stems and blue-green leaves. The leaves have a frilly edge and a more tender texture compared to curly kale. This variety has a mild, slightly sweet flavor with peppery notes.
Nutritionally, Red Russian kale is high in vitamins A and C, as well as iron and calcium. Its tender leaves make it versatile in both raw and cooked applications. It's particularly delicious in salads, smoothies, and lightly sautéed dishes.
Specialty and Less Common Kale Varieties
Redbor Kale
Redbor kale is a stunning variety with deep purple-red leaves that intensify in color as the weather gets colder. It has a similar taste and texture to curly kale but with a slightly nuttier flavor. This variety is not only nutritious but also adds beautiful color to gardens and dishes.
Like other kale varieties, Redbor is rich in vitamins and antioxidants. Its striking color makes it an excellent choice for garnishes, salads, and any dish where you want to add visual appeal alongside nutrition.
Baby Kale
Baby kale refers to young, tender kale leaves harvested early in the plant's growth cycle. These leaves are milder in flavor and more delicate in texture compared to mature kale. Baby kale can come from any kale variety but is most commonly found as a mix of different types.
The tender nature of baby kale makes it perfect for raw applications like salads and smoothies. It's also a great option for those who find mature kale too tough or bitter. Nutritionally, baby kale offers similar benefits to mature kale but in slightly lower concentrations due to its younger age.
Growing Kale: Best Varieties for Cold Weather
Kale is known for its hardiness and ability to withstand cold temperatures, making it an excellent choice for winter gardens. Some varieties are particularly well-suited for cold weather growing:
- Winterbor Kale: A curly variety known for its exceptional cold tolerance.
- Lacinato Kale: Surprisingly cold-hardy despite its delicate appearance.
- Red Russian Kale: Becomes sweeter after exposure to frost.
These cold-tolerant varieties not only survive in chilly conditions but often improve in flavor after exposure to frost, developing a sweeter taste as the plants convert starches to sugars in response to cold temperatures.
Cooking with Different Kale Varieties
Different types of kale lend themselves to various cooking methods and dishes:
- Curly Kale: Ideal for kale chips, sautés, and soups due to its sturdy texture.
- Lacinato Kale: Excellent in raw salads, pesto, and quick stir-fries.
- Red Russian Kale: Great in smoothies, salads, and light sautés.
- Redbor Kale: Use in dishes where you want to add color, such as salads or as a garnish.
- Baby Kale: Perfect for raw applications like salads and as a mild addition to smoothies.
Experimenting with different kale varieties in your cooking can add new flavors, textures, and nutritional profiles to your meals. Don't be afraid to mix and match types to create unique and delicious kale-based dishes.
