kohlrabi – Thom Eagle

The kitchen is alive at the moment. Better than alive; it is thriving. Under the sinks, in a space just high enough for the airlocks, there are two demijohns of bubbling honey-water; on the warm shelf on top of the pass are jars of carrots, asparagus and turnips, each brined with its particular citrus and spice, and murkier pots of peel and trim, ageing into edibility. A bowl of plain water and strong flour teems with fungus and bacteria. Today it smells good and sour, reminiscent of rye and pickle and milk – tomorrow it will smell of yeast, of warmth and buns and baking. In the hot dark, squid entrails slowly change.

We chop and pound dead matter, sow it with salt and starve it of oxygen – and life springs up from these airlocked graves. It’s like bloody Dracula. Maybe the whole coffin-full-of-native-earth thing was to keep him stocked up on the bacteria and fungi which supported his particular microbiome; perhaps a vampire is merely a highly advanced form of pickle. There is certainly something (as they say) of the night about the whole process – if you want to look at it that way. I prefer to see it as a creation myth. Various cultures have given us worlds birthed from the brains of giants, the testicles of elder gods, raven shit and living clay; we create a squawling life from compost and salt – our breath moving over the cabbagey waters.

Chop stalks of kale, broccoli, or kohlrabi; mix in 100g of salt and 50 of sugar to every kilo of vegetable. Squeeze and crush it in, and leave overnight.

Tomorrow, make a paste of green chillies, garlic, spring onion, mint, and fish sauce or seaweed; mix and pound that in, too. Pack into jars, seal tight, and leave for a week. It lives!

They’re funny things, brassicas, capable, depending on context, age and variety, of Italian sophistication, Teutonic rigour or gently British irrelevance. Few gourmands would admit to a love of a broccoli and tuna pasta bake; reconfigure that as purple sprouting, orecchiette and bottarga and you have a death-row meal. Although your basic cauliflower is now gaining in popularity over the fractal, reptilian Romanesque, there is still a rigid hierarchy of cabbages, with varieties like hispi, January King, and that flat stuffable one allowed on to menus never sullied by the honest white, mainstay of coleslaw and kebab shops.

The cabbage, plain and dull as it might be, is one of our oldest vegetables, a gift, as with so many other edibles, of the Romans – I don’t know where they got it from. At one time it would have formed almost the entire diet of the European peasant, from Naples to Nottingham; it’s no wonder we have so many varieties. Luckily, the cabbage takes well to inteference and mutation. The cauliflower, as its name suggests, is a sort of artificially fattened cabbage blossom, allowed to let itself go almost to seed, becoming bloated and corpulent; its sleeker, odder cousin is the kohlrabi. This is one of those vegetables rarely seen outside of restaurants, and has never received an English name. In (I think) Dutch, it simply means ‘cabbage-turnip’, but I prefer Cabbage-Head. Vaguely resembling a root, it is in fact a fat, distended cabbage stalk, with only a few waving leaves and tendrils to remind you of its cabbage-hood. It is crisp, sweet and appley, with only a whisper of mustardy brassical heat, excellent raw in slaws, remoulades and pickles – so much so, in fact, that I’ve never cooked with it, and I’m not sure I want to.

It has a great affinity with aniseed flavours and with fish, and slips well into the sort of fennel-orange-chicory combinations that are your main salad option at this time of year; try finely slicing all of the above, dressing with capers, bitter oil and sweet white vinegar, and serving with crisply seared cod cheeks. Shredded and mixed with scant spoonfuls of aioli, it stands up to thinly sliced raw or cured beef as well as to poached salt ling, flaked through a salad with handfuls of roughly chopped herbs. Lacking these things, or with an abundance of winter vegetables, this mixed pickle is an excellent thing to make. The bitter citrus cuts through the mild funk of fermentation, and the whole thing is like a jar of pale winter sun.

MIXED PICKLE

70 g salt

70 g sugar

a few juniper berries, peppercorns, bay leaves and cloves

1 kohlrabi

2 fat carrots

1 bulb of fennel

4 sticks of celery

1 onion, preferably sweet and white

1 lemon

1 blood orange

3 cloves of garlic

Put the sugar, salt and spices in a pan with 2 L of water and bring to the boil, just to dissolve the salt and sugar. Leave to cool down while you prepare the vegetables.

These can be more or less thinly sliced. I like them shredded, so the whole is more like a spoonable condiment that individual ‘pickles’, but that’s up to you; the lemon and orange should be good and thin, though, whatever else you do. The fermentation will take longer the bigger the pieces are, mind. Pack the veg into a sterilised jar and pour over the brine. Seal and leave somewhere warmish.

In a few days they should start clouding over – this is good. Start tasting soon after, and refrigerate when you’re happy with the pickliness. The lactic sourness should be enough to counteract the bitter lemon.
