Yes, you can make kimchi with green cabbage or other greens. The taste will be different, generally more bitter and less sweet than Napa cabbage kimchi, and the texture will be firmer and crunchier.
Detailed Explanation:
While Napa cabbage is the most traditional and widely used ingredient for kimchi, you can definitely experiment with other vegetables. Green cabbage, also known as common cabbage, is a popular alternative. The key difference lies in the vegetable's inherent characteristics:
- Taste: Napa cabbage has a mild, slightly sweet flavor that ferments beautifully. Green cabbage has a more assertive, slightly bitter taste. This bitterness will be present in the final kimchi, although fermentation will mellow it somewhat. Other greens like kale, mustard greens, or even radish greens can also be used, each imparting its unique flavor profile.
- Texture: Napa cabbage has a delicate, slightly tender texture after fermentation. Green cabbage, being denser, will retain more of its crunch even after fermentation. This results in a firmer, crisper kimchi. Other greens will vary in texture depending on their composition.
- Preparation: The preparation process is generally the same regardless of the vegetable used. You'll still need to salt the cabbage (or other greens) to draw out moisture and soften it before adding the kimchi paste. However, you might need to adjust the salting time depending on the density of the vegetable. Green cabbage, being denser, might require a slightly longer salting period.
- Fermentation: The fermentation process remains the same. The lacto-fermentation process is driven by bacteria that consume sugars and produce lactic acid, regardless of the vegetable used. However, the fermentation time might vary slightly depending on the sugar content of the vegetable.
In summary, while Napa cabbage provides a sweeter, more tender kimchi, using green cabbage or other greens will result in a kimchi with a bolder flavor and a crunchier texture. It's all about personal preference and experimentation.
Pro Tip:
When using green cabbage, consider adding a small amount of sugar or fruit (like apple or pear) to the kimchi paste to balance the bitterness and promote fermentation. This will help mimic the natural sweetness of Napa cabbage and create a more balanced flavor profile.
