coastal advent day 23~





































nigella's yule cake

for the cake

6 large eggs (separated)
¾ cup superfine sugar
½ cup unsweetened cocoa
1 teaspoon vanilla extract
5 teaspoons confectioners' sugar (to decorate)

for the icing

1 cup bittersweet chocolate (chopped)
1 ⅔ cups confectioners' sugar
2 sticks soft butter
1 tablespoon vanilla extract

Method

Preheat the oven to 180°C/gas mark 4/350ºF.

In a large, clean bowl whisk the egg whites until thick and peaking, then, still whisking, sprinkle in 50g / ¼ cup of the superfine sugar and continue whisking until the whites are holding their peaks but not dry.

In another bowl, whisk the egg yolks and the remaining superfine sugar until the mixture is moussy, pale and thick. Add the vanilla extract, sieve the unsweetened cocoa over, then fold both in.

Lighten the yolk mixture with a couple of dollops of the egg whites, folding them in robustly. Then add the remaining whites in thirds, folding them in carefully to avoid losing the air.

Line a Swiss roll tin with baking parchment, leaving a generous overhang at the ends and sides, and folding the parchment into the corners to help the paper stay anchored.

Pour in the cake mixture and bake in the oven for 20 minutes. Let the cake cool a little before turning it out onto another piece of baking parchment. If you dust this piece of parchment with a little confectioners' sugar it may help with preventing stickage, but don’t worry too much as any tears or dents will be covered by icing later. Cover loosely with a clean tea towel.

To make the icing, melt the chocolate – either in a heatproof bowl suspended over a pan of simmering water or, my preference, in a microwave following the manufacturer’s guidelines – and let it cool.
Put the confectioners' sugar into a processor and blitz to remove lumps, add the butter and process until smooth. Add the cooled, melted chocolate and the tablespoon of vanilla extract and pulse again to make a smooth icing. You can do this by hand, but it does mean you will have to sieve the sugar before creaming it with the butter and stirring in the chocolate and vanilla.

Sit the flat chocolate cake on a large piece of baking parchment. Trim the edges of the Swiss roll. Spread some of the icing thinly over the sponge, going right out to the edges. Start rolling from the long side facing you, taking care to get a tight roll from the beginning, and roll up to the other side. Pressing against the parchment, rather than the tender cake, makes this easier.

Cut one or both ends slightly at a gentle angle, reserving the remnants, and place the Swiss roll on a board or long dish. The remnants, along with the trimmed-off bits earlier, are to make a branch or two; you get the effect by placing a piece of cake at an angle to look like a branch coming off the big log.
Spread the yule log with the remaining icing, covering the cut-off ends as well as any branches. Create a wood-like texture by marking along the length of the log with a skewer or somesuch, remembering to do wibbly circles, as in tree rings, on each end.

You don’t have to dust with confectioners' sugar, but I love the freshly fallen snow effect, so push quite a bit through a small sieve, letting some settle in heaps on the plate or board on which the log sits.

MAKE AHEAD TIP:
Make the Yule Log up to 1 week ahead and store in an airtight container in a very cool place.

FREEZE AHEAD TIP:
Make the Yule Log and freeze in a rigid container for up to 3 months. Thaw overnight in a cool room and store in an airtight container until needed.
