When you go to the market or green grocer, you should know how to select mustard greens. They should be free from blemishes, yellow or brown spots. They should have a bright, fresh green look or a lively dark red or deep purple colour.

Storing mustard greens properly extends the freshness of the produce. They should be placed in a plastic bag in which you have made holes and placed in the refrigerator to keep for up to five days. When mustard greens are cooked, they can stay refrigerated for up to two days.

Preparing for consumption

To rid the leaves of dirt and debris for use, place the leaves in a large bowl with ice water and salt and swish the leaves around and repeat twice until all dirt and insects are removed. Finally rinse with cold water only.

Preparing mustard greens for consumption is easy. If you are using the leaves for salads, fold leaves in halves along the stem and cut the folded leaves along the stem discarding the stem. For other methods of food preparation, the stem may remain as cooking will soften it.

Meal ideas

1. Young leaves are used for fresh green salads

2. Cook with red beans or chick peas and rice

3. Sauté mustard greens in coconut oil with crushed nuts and a dash of lemon juice.

4. Sauté mustard greens with slivers of sweet potatoes or slices of tofu.

Safety factor

As a member of the cabbage family, mustard greens contain goitrogen, a naturally-occurring substance that may interfere with the thyroid gland but it would have to be consumed in extremely large amounts or if there is existing iodine deficiencies. When mustard greens are cooked, goitrogen compounds are inactivated. Persons with thyroid problems should not consume collard greens in its raw state.
