From smoked salmon to mince pies, here are a few of Observer Food Monthly's favourite suppliers
Where to buy a good goose
The Cratchits ate one with apple sauce in A Christmas Carol and René Redzepi has a brilliant recipe for roast goose here. Turkey would have been the more exotic choice in 19th-century Britain, goose the more traditional. But in recent years goose has been making inroads in turkey's dominance, the crisp skin and rich, dark meat maintained by the fat that makes for deluxe roast potatoes. Find a good supplier such as Seldom Seen, who have 5,000 well looked-after geese roaming their Leicestershire farm. seldomseenfarm.co.uk
Where to buy a chocolate treat
Paul A Young Christmas treats are particularly indulgent this year, especially the rich plum pudding brownie (£5.95), boozy plum pudding dome (£5.50) made with armagnac-soaked prunes and port and brandy mincemeat, and gold, frankincense and myrrh bar (£5.95) made with flecks of gold leaf. paulayoung.co.uk
Where to buy the best puddings
Bath-based Richard Bertinet is offering puddings in two sizes (the smaller costs £10), which you can pick it up at his bakery or order online. Also recommended is the award-wining Figgy's, with husband-and-wife team Richie and Jo Evans producing small batches of boozy Christmas pudding using local ale and cider brandy, sold online and at stockists in the area. A medium 550g pudding costs £14.
In Yorkshire, Betty's sells a dizzying variety of seasonal treats, not just puddings and mince pies but also Christmas fruit cakes, chocolates, biscuits, tea and coffee. Buy from any of their six tea rooms or online. thebertinetkitchen.com; figgys.co.uk; bettys.co.uk
Where to buy the best fish
Rick Stein speaks highly of Quayside Fish, a Cornish fishmonger that buys only line-caught fish from day boats. They sell marvellously fresh fish and seafood at their shop in Porthleven, and throughout mainland UK via a next-day delivery service. Get your lobster, oysters, smoked salmon, John Dory – and many more fish – here.
Steve Hatt, a fourth-generation London fishmonger based in Islington, does things simply and well. No website, no Facebook, no Twitter; just the small, brilliantly stocked shop on Essex Road, where you can pick up fresh scallops, wild Scottish halibut, sole and whatever else you need for the Christmas season. quaysidefish.co.uk; Steve Hatt, 88-90 Essex Rd, N1 8LU, 020 7226 3963
Where to buy the best birds
Recommended by restaurateurs including Raymond Blanc, Leamington Spa butcher Aubrey Allen's highlights this year include free-range bronze turkeys from Caldecott farm and locally sourced Warwickshire geese and cockerels (last orders 13 December).
In Scotland Simon Howie, an award-winning butcher with outlets in Auchterarder and Perth, is putting together Christmas dinner packages (the "wee" pack costs £38). They deliver throughout the UK (last orders 12 December). In north London, Meat N16 won the south of England butcher's shop of the year award for 2012. It also has a wine room at the back, so as well as free-range turkey and geese from Essex, you can stock up on bottles to match (last orders 20 December). aubreyallen.co.uk; thescottishbutcher.com; meatlondon.co.uk
Where to buy the best smoked salmon
If you're stocking up on smoked fish this Christmas, to serve as a starter or in a festive brunch, it's worth sourcing the best. And the best, according to Richard Corrigan, Myrtle Allen and others, comes from Frank Hederman, who has been smoking wild Atlantic salmon – as well as eel, mackerel and mussels – in County Cork for 30 years. At Belvelly Smoke House in Cobh, Hederman uses beech chips instead of oak, imbuing the fish with a milder flavour, and slices the fillets with incredible precision. The results, which Hederman believes should be eaten unaccompanied by pepper or lemon, can be purchased via frankhederman.com.
Where to buy the best cheese
Few places can compete with London's big two. Neal's Yard Dairy's stichelton (similar to stilton, but unpasteurised) is an ideal Christmas cheese and La Fromagerie has a great online 'cheese room' which allows users to search by animal and country of origin.
Iain Mellis opened his first cheese shop in Victoria Street in Edinburgh 20 years ago. Now he has six around Scotland, with outlets in Glasgow, Aberdeen and St Andrews, selling farmhouse cheese from Spain, Italy and France as well as closer to home. For Christmas, they recommend two great Scottish cheeses, Lanark blue, made with raw ewe's milk, and anster, a crumbly cheese with a full finish.
Winner of an OFM award in 2011, the Cheese Shed's mission is to make West Country cheeses (beenleigh blue, ogleshield, heligan) more widely available. Each year they put together a Christmas box: pick one up from their new shop in Bovey Tracey, or order online – they deliver nationwide.

Where to buy the best mince pies
It's hard to better the mince pies from St John Bakery, the bread-and-bun wing of Fergus Henderson's much-loved St John restaurants. You can buy direct from the bakery on Druid Street, London SE1, on Saturday mornings, or via the restaurants in Smithfield and Spitalfields. stjohngroup.uk.com
What to buy: the ultimate Christmas cheese
Christmas isn't complete without a stinky French fromage and the most meltingly voluptuous cheese of all is the unpasteurised alpine vacherin mont d'or, perfectly packed in its own spruce box. You can eat it with a spoon and maybe a sweet sticky wine. Available everywhere.
