La Goutte D’Or, a world apart from the swankier markets. This is full-on ethnic Paris – edgy and vibrant. On the edges of the market, police struggle to clear illegal hawkers. Cigarette sellers hide their stashes in litter bins. Couscous is a typical dish of the day in local cafes.

Visit on a Saturday morning. Also try Jambo or Le Palanka restaurants for top-notch food from Africa.

‘The year ahead is mysterious. What lies in store for business? How will London cope with the Olympics? 2012 is an especially tricky year to predict. Even the seasons are out of kilter, with last year officially the second warmest since records began.

On the market, however, January is reliably offering its seasonal highlights. The first forced rhubarb has arrived, with also both blood and Seville oranges for their fleeting season.

A new wholesaler, Covent Garden Supply, has taken up a new position on buyer’s walk with a strong track record in catering supply. The company offers a wide selection, including Datterini and San Marzano tomatoes – lines previously supplied by Italian importer L’Orto di Sorrento, who have now sadly ceased trading.

Their other produce on my visit included fine lemons from La Costiera, blood oranges, tardivo, fennel, celeriac, spinach, butternut squash, potatoes, onions, swedes and turnips. “Italy, Egypt, America, China … it’s a United Nations,” remarks director Paul Whyman.

Elsewhere on the market, the usual winter staples are abundant. Wild mushrooms, chestnuts and cranberries are at their best. Madjoul dates and Agen prunes are piled by the box.

Brassicas include sprouts, tops, cauliflowers, kales, cabbages and excellent purple sprouting. “It just keeps growing and growing,” explains farmer and purple sprouting specialist Martin Sanders from Cherry Fields farm in Worcestershire. “The kids are picking in their jeans and t-shirts because it’s so mild.” His crop is sold by wholesalers including Premier Fruits.

Squashes are coming to an end, but traders such as S Thorogood & Sons still have a varied selection. For spuds, new crop Cyprus potatoes are best for flavour.

C & C Fruit boast some more unusual items such as Piccolo parsnips and other minis including turnips, patty pans and leeks. Highlights at The French Garden include romanesco, top notch winter salads such as red Batavian and speckled lettuces, Swiss chard, cime di rappe and smoked and rose garlic. The European Salad Company stocks some similar quality produce including first rate French watercress and crosnes (Chinese artichokes).

For fruit, expect English Cox, Braeburn and Bramley apples plus Conference and Concorde pears. Pomegranates, quinces, clementines and satsumas are at their best. The South African season for grapes, peaches and nectarines is in full swing. Strawberries hail from Morocco, Holland and Egypt.

So what are the traders’ predictions for 2012? Opinions are mixed, although a consensus is that trading will be tough. The Olympics, believes Paul Whyman, will complicate transport for companies like his. Eddy Barrett, salesman on H G Walker, is more upbeat about the event: “Theoretically it will make it better but we’ll have to see how many of the boys get contracts.” ‘

Learnt clever techniques, including their Thai Basil dipping sauce. To make it, blitz the leaves with grapeseed oil, then filter through muslin. Use this oil to make a mayonnaise-style dip. Start with egg yolk, lime juice, salt and a little fish sauce, then slowly incorporate the oil.

The vinegary capers change character, from land to sea. Mixed into the samphire, flash fried in butter, they become juicy seaweed-y nuggets.

I would never mess much with samphire, but this match is a winner. Just add a squeeze of lemon juice to complete the buttery, vinegary juices.

I would grow this plant even if it never fruited. The colour and texture of those bristly red stems are unlike anything else in the garden. It’s a perennial from the raspberry family, and the berries are a delight. Just slightly sticky, sweet and special.

Forcing rhubarb

Roasted them to have with mackerel. The trick with cooking the stalks is to keep their firm texture, rather than turning mushy. Roasting or grilling both work. To roast, chop into chunks, then lay in a roasting tin with a few splashs of water. Sprinkle liberally with brown sugar.

For recipes for coriander leaves and stalk, had a go at a coriander-heavy chutney, inspired by a recipe in The London Cookbook. Actually, it felt more like a pesto to me – thicker paste, very delicious, good hit of green chilli.

To make it, you dry roast a spoonful of cumin seeds then a handful of peanuts in a heavy frying pan, then grind them up. Then, in a blender, whizz garlic and green chillies, add the peanuts and cumin, sugar (jaggery), salt, lemon juice and then bunches of coriander, chopped down to just above their root.

I deliberately haven’t included exact quantities. This is the kind of recipe that needs a bit of instinct to balance the flavours how you like it.
