I had forgotten my previous recipe for chocolate mousse. This time, making a decent quantity (for pudding following the fish stew), I used about 175 g of Green & Black's dark chocolate, with five egg yolks, and five whites.
What alarms me about mousse-making is that the melted chocolate always stiffens, and appears to acquire a grainy texture, when I stir in the egg yolks. The finished dish is fine, if somewhat stiff too. This time, I tried very hard to avoid this effect. I gave the chocolate time to cool; I loosened it with about 4 tbsps of double cream; I loosened it further by beating in a little of my stiffened egg white. I beat the egg yolks, and stirred them in little by little. The mixture seized up again.
The finished mousse was the most mousse-like (light in texture, I mean) chocolate mousse I have ever made. But it was also grainy. I do not understand why.
