Collard Greens: What are they?

Collards feature hard stems and dark green, fan-shaped leaves. They belong to a group of plants that also includes mustard greens, turnips, and kale. Additionally, they frequently share the same characteristics and are prepared in the same manner or using the same ingredients (at least in the South of the United States, where they are most popular).

Ham, beans, okra, and other items that require slow cooking, such as simmering, braising, or steaming, combine well with collard greens. Although they require special attention before and after cooking to achieve the greatest texture, they are not difficult to deal with.

Collard greens are the name we give to the leaves we consume. Collards are a type of vegetable with large, emerald-green leaves and tough stems that must be removed before consumption. They are related to kale, mustard greens, and cabbage and can be prepared similarly. Southerners frequently serve collard greens as a side dish because of their reputation for heartiness.

In addition to onions, vinegar, pepper, salt, smoked and salted meats (such as ham hocks and bacon), collard greens are frequently prepared this way. The stiff leaves are frequently used in braises and soups since they don’t disintegrate when cooked for an extended period. They can also be included in salads or wraps that employ greens instead of bread.

  • Use more than one bag if you’re cooking a lot of collard greens at once.
  • Use the collard greens within 10 to 12 months after freezing them. To keep track of how old the greens are, mark the bag with the current date. Try to eat greens within a year of freezing them for the best freshness and flavor!
  • Use your greens as soon as possible if you don’t blanch them.
