Christmas has crept up behind me and kicked me in the baubles and now I find I don’t have the time to bake the usual British classics we all know and love. Just because I’ve left it too late to make and mature a Christmas pudding and cake, it doesn’t mean this year’s table can’t sparkle with the spirit of Christmas cheer.

2012 is the year I’ve decided to go continental, with a Bûche de Nöel taking centre stage. This will, undoubtedly, come as a blessed relief to my nephews, who are yet to warm to the boozy, rich and hearty indulgence of my Victorian Christmas pudding. Once the brandy flame puffs out, all interest is entirely lost and they’re asking if there’s any mint choc chip ice cream instead.

With any luck, this year’s more child-friendly chocolate and chestnut offering will keep their minds off the freezer contents, by diverting their attention to my meringue mushrooms instead. Mint choc chip might well be delicious, especially when stirred for long enough to make ice cream soup, but festive it ain’t.

Don’t be scared of rolling up the log, if it looks less than neat, you can always mask mistakes by being more liberal with the chocolate ganache coating than originally planned. It’s one of those jobs where a gung-ho attitude will fare you better than any amount of measured caution.

The mushrooms are ever so slightly fiddly, but are cute enough to be worth the effort. And come on, it is Christmas after all, so some boats ought to be pushed out, even if you have left them in the dock until the eleventh hour. As well as the meringue mushrooms, I adorned my Yule log with some washed and dried clippings from the Christmas tree, but sprigs of fresh rosemary will look equally enticing.

It’s best, though not essential, to make the meringues the night before so they have time to properly dry out.


Preheat the oven to 100°C/gas mark 1/4. Line a baking tray with parchment or silicone paper
Whisk the egg whites with the salt until stiff before gradually adding the sugar, a little at a time, whisking between each addition. You should be left with a stiff, glossy and pipeable meringue
Spoon the meringue into a piping bag fitted with a plain, large nozzle and pipe the mushroom caps – little rounds of about 2-inches wide. Next, pipe the mushroom stalks, by piping little upright peaks. Bake for 1 hour, turn off the oven and leave to cool and dry out – preferably overnight
Melt the chocolate and paint the underside of each cap with it, using a pastry brush. Glue the stalks on to the caps with a little more melted chocolate (you can, if you need to, create a cone-shaped hole in the caps with a small knife, to make attaching the stalks easier)
Leave the mushrooms to set upside down, before lightly dusting their tops with cocoa for a more naturalistic look
For the Bûche de Nöel, preheat the oven to 180°C/gas mark 4. Line a 9” x 13” roulade tray with baking parchment
Whisk the egg whites and salt until stiff. Using the same beaters,but in a separate bowl, whisk the yolks and sugar until pale, thick and creamy
Whisk the chocolate and chestnut flour into the sugar and yolks before vigorously beating in a couple of tbsp. of whipped egg whites, to slacken the mixture
Gently fold in the remaining whites with a large metal spoon, being careful not to lose any of the air. Pour the batter into your prepared tin and bake for about 20 minutes or until an inserted skewer comes out clean
For the chestnut cream, simply whip the cream and mix in the chestnut purée. Upturn your chocolate and chestnut roulade on to a sheet of baking parchment and spread over a generous layer of the chestnut cream
Roll up the cake, using the parchment to help you. Transfer your roll, seam side down, on to a plate or board and pop in the fridge until ready to ice
Now make the ganache topping. I like to blitz my chocolate in the food processor for speed, but you can chop you chocolate with a knife if you prefer
Transfer the chopped chocolate to a heatproof bowl. Place the sugar and cream in a saucepan and stir over a gentle heat until the sugar has melted. Increase the heat and bring to the boil before taking off the heat and leaving to stand for 1 minute
Pour the hot cream over the chopped chocolate and mix with a rubber spatula until smooth, thick and glossy. Leave to cool slightly before spreading it all over the roulade
To make it look more like a log, scratch the surface of the ganache with a knife or fork for a bark-y effect. Pop it back in the fridge to set
Decorate your serving plate/board, if you wish (I painted mine with textured melted chocolate and added a few sprigs of Christmas tree) before carefully transferring the cake into the centre. It’s easiest to employ a large palette knife or fish slice to do this. Drift the whole board with sifted icing sugar and/or edible snowflake lustre
Place your meringue mushrooms in clusters on and around your Yule log and serve. Please remember that fresh cream can only be left out of the fridge for up to 4 hours
If you want to leave your Bûche de Nöel out for longer, I would suggest swapping the cream for chestnut buttercream (75g soft, unsalted butter, 150g sifted icing sugar and a few generous spoonfuls of chestnut purée whisked together until soft, light and fluffy)
