Wild Garlic, Gooseberries and Me: A chef’s stories and recipes from the land. Denis Cotter
but you may have come across it as ‘Texsel greens’, a very unglamorous name given to it by people trialling it as a crop in, er, Texas, would you believe? Ultan first grew it to fill that gap in mid-to-late winter. It can survive outdoors in our summer, but the fields and tunnels are full of greens then. So instead, he grows it in a tunnel in the dull days of November to February, to give us some badly needed variety at that time, something softer and lighter than most winter greens.
We harvest it in two ways for Paradiso: firstly as a cut-and-come crop where small-to-medium leaves are picked from closely sown plants; and secondly as a plant grown to full maturity when the leaves are almost the size of spring cabbage. The younger, cut-and-come leaves are close to spinach in texture, and can be used in almost the same way, bearing in mind that they do have a slightly tangy cabbage flavour. This works well with the sweetness of tomato and garlic, and it is comfortable too with the zing of ginger and some of the sweeter spices like nutmeg, paprika, fennel and cinnamon.
Even at full size, the leaves are relatively soft, somewhere between a coarse spinach and spring cabbage. This is a refreshing food to have in the depths of winter, when you want the flavour of fresh greens but are not in the mood for the full-on hit of kale. You can even eat the sprouted shoots, which cook like sprouting broccoli. The large leaves make a good wrapping for dolmas, timbales and terrines, but they are best cooked simply in any way that works for spring cabbage, especially stir-fried and seasoned with sesame and soy sauce.
Flowering brassica – the true cabbage royalty
When I think of great brassica, however, it isn’t the headed cabbages I dream about at all, but the flowering heads of broccoli and the loose leaves of kale. It is astonishing that purple sprouting broccoli has been grown for hundreds of years, yet it has remained relatively obscure in recent times. Meanwhile, the vegetable generally known as broccoli or, properly, calabrese, has taken over the Western world in a mere thirty years.
On the other hand, sprouting broccoli has the drawback of being a vegetable that doesn’t accord with the average supermarket buyer’s criteria. It has a long growing season, is time-consuming to harvest on a large scale, and it needs to be eaten when very freshly picked. But for the consumer, the flavour of sprouting broccoli has an intensity, richness and complexity that shows up the big-headed green version as the one-dimensional thing it is.
It doesn’t take much imagination to see how those attributes can be seen as positive attractions to those whose main priority in food is not mere convenience. This is a vegetable that sits in the ground over winter, then produces the most beautiful and intensely flavoured shoots in late winter, and continues producing more for eight to ten weeks. Its arrival at this lean time of year gives it a very special place in the hierarchy of all vegetables. There are varieties that crop even earlier, depending on the mildness of the winter, and others that go on producing into late spring. This is an area where the breeding of varieties to extend the season can only be seen as a good thing. The autumn in which I wrote this piece was so mild that many broccoli plants due to sprout early, as in shortly before Christmas, were already putting out a crop in early November. What is a grower, or a cook, to do? Scold the plant for unseasonal behaviour and ignore the crop? Or be grateful for such an early treat? I value the principle of seasonality as much as anyone, and I love those vegetables which remain resolutely and stubbornly seasonal. But there is a big difference between growers using their skill and knowledge to extend the season of a plant and a supermarket flying the stuff in from the opposite hemisphere because we can’t go a week without it. It is mainly because of this intelligent and useful extending of sprouting broccoli’s season that we are finally beginning to see it more frequently in markets and even in some supermarkets.
The last time I wrote about purple sprouting broccoli, in Paradiso Seasons, I suggested that the only hope for wider recognition of its virtues was if both the public and the growers viewed it as a vegetable on a par with asparagus in terms of perceived value and price. I didn’t know then that in Italy, where it has been loved for centuries, it has long been treated as such when sold at markets. It was even referred to as ‘Italian asparagus’ in eighteenth-century England.
Purple sprouting broccoli has a big rich flavour; a little bitter, yes, but with that essential innate sweetness too. It is great in stir-fries with hot spices like chilli and ginger, but is just as comfortable in pasta dishes with the sweetness of tomato or peppers, and herbs like thyme, basil and oregano. It works with most cheeses, but especially soft sheep’s milk cheeses like Knockalara, or mild blues. One of the nicest and simplest ways to prepare it is to simmer it in a small amount of water in a covered pan until just tender, and then dress it with olive oil, salt and pepper. This simple dish is equally good whether served at room temperature or piping hot.
Cime di rapa, or broccoli raab, is a somewhat similar vegetable, but it is grown more for its leaves than for the flowering stalks. The leaves are wonderfully bitter, yet cook as quickly and as softly as spinach. When cooked in olive oil, the leaves shrink quickly but become the most darkly vibrant shade of green. The edible stalk is sweeter than the leaves, which makes the combination such a deliciously balanced flavour. The skin of the stalks can be slightly stringy, so it’s best to either peel them or chop them finely. As I write, we have only eaten a trial crop, but it is a vegetable I am very excited about for the coming years. It is wonderful in pasta, as a perky side dish for a comforting risotto and cooked with the tomatoes and chillies that complement dark greens so well.
There is a great love of flowering brassica in Chinese cooking, and most of the favourites are from a range of greens going under the general name of choi sum. One that we have taken to using in the restaurant is Chinese broccoli, sometimes known as Chinese kale. (Well, it isn’t technically one of the choi sum family at all, but it is grown and used in the same way.) For some reason, faced with the choice of names, Ultan and I decided to go with ‘kale’ at first. I think he had kale on his mind that week, trying to find ways to make sure we always had a couple of kale varieties on the menu.
To confuse the matter even more, if you are lucky enough to come across this gem in a Chinese restaurant, as I did in a wonderful place in London doing a modern take on dim sum, then it will probably be called ‘gai lan’. Probably. Don’t bet your house on it. It might be ‘kai lan’, or any of a number of variations on the two. Outside of horticultural books, these terms can be more casual tools for communication. We choose one and go with it. That way, I know what the grower means, my cooks and floor staff understand what I mean and, hopefully, so do the people eating in the dining room. Nonetheless, when it came to serving the vegetable, I reverted to ‘Chinese broccoli’. Next year, I’ll go for broke and use ‘gai lan’. It must be a brassica thing, this confusion over names. I’m sure the rest of the vegetable world is much more conformist.
While not exactly a fast grower, Chinese broccoli gives results much faster than its Western cousins, putting out flowering stems with soft leaves attached. As with sprouting broccoli, these stems are the prized part of this amazing vegetable. It has that classic combination of sweetness and slight bitterness, and the young leaves are delicious too. The texture of the stem, picked at the right time, is tender and juicy, with a little bite. In the pantheon of greens, it has it all. It is often picked as a young whole plant, when every part can be eaten, and can be presented on the plate as one piece, which looks very striking.
Chinese broccoli has strong enough flavours to carry quite a lot of spices, and works especially well when flavoured with chillies, ginger, soy sauce or sesame oil. But if you think of it as having a character close to sprouting broccoli, then you can see how it can be used with European seasonings, with garlic, tomatoes and herbs, even with cheeses, as well as in the usual contrasting role with risotto and other comfort foods. It is great with eggs too, especially served straddling a soft omelette.
The timely revival of lowly kale
Not fifteen years ago, the only kale to be found was the curly green one. Even then, most people believed it to be fit only for cattle; a tiny minority enjoyed it from their own gardens, but it never showed up on shop shelves. Kale may have suffered from its association with poverty and hunger, something it shares with the wonderful but often derided swede turnip.
