Chocolate Mousse Cake

Intro

1 part Anita, 1 part my Mum and 1 part Rosalie :) 

This recipe has lovely layering around it and the intro may well end up longer than the recipe! Back in the day, when I was a kid, my Mum and Dad used to have these lovely dinner parties. Graham Greig (work colleague of Mum's) and Anita (his wife) were regular guests. Anita made this gorgeous Chocolate Mousse cake once and, fortunately for us gave the recipe to Mum. Apparently, its an old Hudson and Hall recipe and I did track it down many years later but this modified 'made up' version is heaps easier to make. 

Mum used to make this Mousse Cake for high days and holidays using sponge cake and a packet mousse mix and lumps of cake rather than layers. So not the Hudson and Halls recipe as such, or method actually, which involved many fine layers of homemade cake and mousse and hours of faffing about. The original recipe is hideously expensive to make and we were not a wealthy household but we took the concept! 

Then one Christmas in the mid 80s I put my finger into a bowl of chocolate mousse that Rosalie Blake's son Jeremy had made from a recipe he got from their neighbour Sarah Hodge in Manakau. Stunning. Just 1 word for it. So, the recipe entered its final incarnation and I use Rosalie / Sarah's mousse recipe, Mum's method and Anita's concept. This is only made on very special occasions - birthdays really. But wait - there is a final twist to the tale ... years later, my widowed Mum and Anita's widowed husband Graham got married. and one of the first times I went for a special meal (Christmas or something) I took a Chocolate Mousse Cake ... and that's when I found out that the dessert was actually based on Anita's recipe. 

Recipe

Melt gently together in a double boiler (or a microwave if you are impatient) until a nicely combined smooth mixture - don't over melt or over stir.

• 300g good chocolate*
• 125g unsalted butter (salted works just fine)
• 25g cocoa powder (yes use a scale)
• 50g castor sugar

Separate

• 5 eggs - throw 1 yolk away (or feed it to the cat)

Add 4 lightly beaten yolks to the chocolate mixture and stir until just combined - then stop immediately (or mixture may curdle) Beat together until stiff (but not quite pavlova stiff):

• 5 egg whites
• a pinch of salt

Gently fold into the chocolate trying not to smash too much air out.

Whip cream until soft peaks form (don't over whip because it makes it harder to work with)

• 300 ml cream (whipping cream / double cream - don't know what else its called)

Gently fold this into the chocolate mixture as well, taking care not to smash the air out. 

Take some cake** and break it into golf ball sized pieces. Get a spring form tin and put a thin layer of mousse on the bottom of the tin. Put bits of cake in and pour mousse in the gaps, then plonk more cake and more mousse in until the tin is full. If you use a large tin the cake will be shallower, if you use a smaller tin the cake will be very deep. Its best to use a larger tin because this is a very big dessert cake that feeds about 10 (or 4 teenage boys). 

Cover it with tin foil and refrigerate until firm. At least 6 hours - preferably overnight. When ready to decorate, lift tin foil off, slide a hot knife around the edge of the tin, loosen the spring form tin, take tin off, place a serving plate on top and tip cake and plate upside down. Remove the base of the tin by sliding a hot knife underneath it. Smooth the top if desired with a hot knife. Decorate with whatever you like. I often use piped whipped cream and halved, hulled strawberries or tinned mandarin segments. My kids love broken flaked chocolate or Belgian seashell chocolates or Ferrero Rochers (yes - the bambini are horribly spoilt but they love me so its all good). 

* Good chocolate means not compound chocolate and not that crappy Cadbury palm oil one but real chocolate. Whittakers is great. Milk is perfect or sometimes I use 50/50 milk and dark Ghana. Don't only use a dark one or it will be unpleasantly bitter. If the mousse tastes grainy or doesn't form a delightful creamy smooth texture it is usually crappy, cheap, nasty chocolate (and I've been caught out a few times). 

** I usually buy a plain trifle sponge or pair of round sponges from the supermarket but I sometimes make a chocolate sponge. It makes a firmer cake which is a bit more filling.
