1. Chocolate: Ensure you use COOKING chocolate, not eating chocolate. Cooking chocolate (baking aisle) is made for cooking with - melts smoothly and is thinner than eating chocolate. If you use eating chocolate, the mousse is denser (I tried).
Bittersweet dark chocolate and 70% cocoa dark chocolate is best to get a good chocolatey flavour. The 70% cocoa sold at supermarkets in Australia is ideal (Nestle Plaistowe, Cadbury and Lindt 70% all work well) - these are bittersweet chocolates.
2. Cream: Must use whipping cream (there are some creams only for pouring that don't whip). Must be full fat - now is not the time to go low fat!
3. Chocolate Shavings: Use a small knife and scrape at a low angle on the flat side of a block of chocolate.
4. Eggs tip: It's easier to separate whites from yolks when eggs are cold, but whites at room temp fluff up better when closer to room temp. So separate the eggs when fridge cold then set aside while you prep the other ingredients to let the whites come to room temp a bit.
5. Beaten whites consistency: Egg whites can be beaten to: soft peaks, firm and stiff peaks. We want the middle one - firm peaks. This is when you have a "elf hat" floppage at the top of the peak (see video). If it stands straight upright without the little hook then it's stiff, not firm (still works fine but it won't hold up as well after a few days in the fridge). If you do not get any type of peaks at all, then keep beating!
6. Storage: Best within 2 days but keeps for a week in the fridge with only a slight reduction in aeration.
7. Nutrition per serving. Makes 4 x 1/2 cup (125ml) servings. It is quite rich!
