Growing Black Palm Kale
Black Palm Kale have been cultivated in Italy since at least the 1700’s, and it still plays a big role in the southern Italian province Campania’s, culinary history. Today it is the most widely grown kale in Italy and an essential ingredient in the famed Tuscan Soup Rabolita.
It has long, strap-shaped foliage that is dark blue-green in color, and it is frequently called “dinosaur kale” because of the bumpy, savoyed texture of its leaves, reminiscent of reptile skin. When leaves are harvested from the bottom of these plants, they take on a palm tree-like appearance as they grow, which account for another of its common names, “palm kale.”
Other names are Cavolo Nero, Nero di Toscana, Tuscan Kale, Lacinato Kale, Dinosaur Kale, Italian Kale.

Because of it’s excellent flavour and texture, black palm kale is the most sought after kale by cooks. With its sweet flavour and little bitterness, it is a favourite for soups and stews, and is also one of the traditional ingredients of minestrone. Young leaves can be eaten raw in salads.

Freezing black palm kale
Black palm kale can be frozen, but it keeps its flavor best if blanched or otherwise cooked first.
That’s because enzymes present on raw produce remain active after freezing, and will alter the flavor or texture of raw frozen produce.
If you tend to run out of room for storing your garden’s bounty in your freezer, a good backup plan is dehydration.
Like many other garden veggies, black palm kale can be dried in an oven set at a low temperature, or in a food dehydrator. Refer to the instructions on your dehydrator for heat and time recommendations.
