Chocolate & Pear Yule Log

You must. This isn’t a last-minute dessert. The mandatory overnight chill is non-negotiable for it to set properly and develop its flavour. You can make the entire log 2-3 days in advance. Add the icing and decorations up to a day before serving.

Keep it refrigerated at all times, loosely covered with a dome or in a large airtight container to protect the icing. It will be at its best for up to 4 days. The mousse sets firmly but remains creamy.

Yes, but strategically. Freeze the un-iced, assembled log, tightly wrapped in several layers of cling film, for up to a month. Thaw overnight in the fridge before icing and decorating. Do not freeze the iced log, the glaze will weep and lose its sheen.

Not yet. The mousse mixture will be quite loose – that’s correct. It sets in the fridge. The key is ensuring your egg whites are whisked to stiff, glossy peaks and that you fold with a gentle, confident hand. If the whites were even slightly floppy, the structure will suffer.

You likely over-baked it. At 10-12 minutes, the surface should look set and slightly bubbly, but still pale. The moment it starts to take on a golden hue, it’s over. It continues to cook on the tray. A dry sponge makes assembly harder.

Use firm, ripe pears like Williams (Bartlett) or Comice. Avoid overly juicy varieties like Conference, which can make the layers soggy. The pears should hold their shape when sliced thinly.

Finely chopped hazelnuts or pecans work well. For a nut-free version, simply omit them and bake the sponge on plain parchment. You’ll lose a subtle crunch, but the world won’t end.

This happens if the cream was too cold or you stirred too vigorously. To rescue it, add a teaspoon of just-boiled water and stir gently until it smoothes out. Repeat if necessary. To prevent it: melt the chocolate, let it cool slightly, then stir in room temperature cream.

Two pro tips: 1) Use a long, thin-bladed knife dipped in very hot water and wiped dry between each slice. 2) For the cleanest cuts, score the icing first with a sharp knife before pressing down through the layers.

The tin is crucial for the classic rectangular “log” shape and compacting the layers. If you’re in a bind, you can shape it freehand on cling film, roll it tightly, and twist the ends like a Christmas cracker. It will be more rustic (read: slightly messy), but charming.

The traditional French mousse relies on raw egg whites for its airy texture. If you’re uncomfortable with this, you can use pasteurised egg whites from a carton, whipped as directed. Do not attempt to cook or “safeify” the mousse mixture, it will ruin the texture.

Work quickly. Have the unmoulded log ready on a cooling rack over a tray. The icing should be fluid but not hot. If it thickens mid-job, briefly microwave it for 5 seconds or place the bowl in a bath of warm water. It’s better to have a slightly uneven, “bark-like” texture, it’s part of the charm.
