Chocolate Yule Log Recipe from Hakkasan’s Executive Pastry Chef

Yauatcha LogThere is a draft post hovering in the background about 12 incredible yule logs created by some of London’s top pastry chefs, that I had a preview of during the summer and some of which are now on sale. That will have to wait until the weekend. For now, if you’re quick, you still have the chance to learn how to make your own in London at the Spirit of Christmas Fair at Kensington Olympia. Or, you can have a go at making it for yourself from the recipe below. The plus in heading to Olympia is you’ll get to take one away per table! And, importantly, a piece to try while you’re there. UPDATE: There are no more buche demonstrations during the show but there are still demonstrations being lead by chefs from the Savoy (not in the Hakkasan Group) and you can always make the recipe yourself below!

For the remaining days of the Spirit of Christmas (until this Sunday) there will be chef sessions each day, though sadly no more from Graham or his team.  The workshops on Wednesday were surprisingly quiet and unworthily so.  Unlike food shows where the demonstrations and the workshops are the draw, at the Spirit of Christmas it is all for filling your stockings with artisan gifts that are not common on the high street. It definitely makes unique shopping easier, but the workshops offering such a high calibre of hosts are definitely worth attending too. More so if you get to take home a gift from it!


Hakkasan was founded by Alan Yau who started his career in restaurants with Wagamama in 1992. Long ahead of its time in casual dining it was a catalyst for change in a then-staid restaurant scene and one of the reasons behind Yau receiving an OBE in 2006 for services to the restaurant industry.  Five of the Hakkasan Group’s restaurants have been awarded Michelin-stars: Hakkasan Hanway, Mayfair and New York, HKK and Yauatcha (London). These are all high-end Chinese restaurants, with the latter also offering a beautiful-looking, ever-changing and boundary-pushing selection of patisserie to eat in or take away, as well as their own range of chocolates made in-house.  For the past three and a half years Graham Hornigold has headed the sweet stuff for the group as Executive Pastry Chef.

Graham Hornigold, Hakkasan Group

Hornigold earned his stripes at a variety of Michelin restaurants, most notably within the Mandarin Oriental, Hyde Park, Knightsbridge and then at The Lanesborough Hotel where he won a host of awards. At Hakkasan he works with the restaurants in the UK and abroad on a variety of styles of desserts. For Christmas at Yauatcha they’re offering slices of the delicious chestnut yule log that we finished off in the Home & Garden Workshop at Spirit of Christmas. I loved this buche, testament to this was the fact I polished off several more slices last night despite judging several rounds of the International Chocolate Awards in the afternoon. If I was going to make it myself I’d sub the milk for more alcohol, but if you’re making it for the first time following the recipe below will deliver you a wonderful Christmas dessert and one you can make in advance and freeze leaving just the final decoration for Christmas morning.
