FAQs

Does it matter what chocolate I use?
Use 68, 70 or 80 per cent cocoa solids – a really good quality dark chocolate is best. I wouldn’t use milk chocolate or anything too sweet because you wantthe mousse to be punchy. Valrhona is one of the easiest good quality chocolate brands to find, but there are many out there, so you can pick and choose the one you like.

Can I use eggs straight from the fridge?
Make sure they’re at room temperature, not cold, because otherwise the cold egg sets the chocolate.

Why can't I add all the eggs whites at once?
Put about a quarter to a third of the egg white into the chocolate mixture first. The reason we do that is to loosen the texture of the chocolate mix so it’s easier to fold in the rest of the egg white. Do that for any soufflés or mousses – it makes it easier to bring the two mixtures together. You can be quite vigorous with your initial blending. I use a whisk for the first addition and beat it all in, then gently fold in the remaining egg white with a large metal spoon or spatula.

How can I jazz it up?
When you’re mixing in the egg yolks, you can make it a little bit adult with a splash of rum, Grand Marnier or whisky. Or you can grate in some orange zest – make it your own.

How should I serve it?
You can go posh and do a wonderful quenelle with one big spoon, rather than faffing around with two spoons. Dip it in hot water, then draw the spoon on its side towards you through the mousse to make a lovely rocher. If you’re doing it for the family, though, presentation doesn’t really matter. You can also make individual mousses but it’s one of those desserts that’s great if you just bring it
to the table in a big bowl

  1. Prepare the mousse up to 2 days ahead. Store covered in the fridge until ready to serve. Leftovers will keep covered in the fridge for several days.

  2. Don’t whip the whites until you’re ready to use them. Adding the 2-3 tbsp (optional) sugar to the egg whites helps stabilise the foam, making it less likely to deflate when folded into the chocolate mixture.

    A large, flattish metal spoon is the best tool for folding in the whipped egg whites – it cuts through the mixture better and moves more of it without crushing the air bubbles. Wooden spoons can harbour grease that will deflate the bubbles.
