AUTHENTIC TIRAMISU

Steps:

• Whisk egg yolks and sugar together with an electric whisk until moussey and creamy looking.
• Add vanilla seeds which you have scraped out of the pod.
• Add mascarpone and beat again.
• Gradually add the alcohol and keep whisking until it looks nice and shiny and thick - don't make it too runny. Save some of the booze to put in the coffee mixture - about 2 - 3 tbs
• Pour the coffee and remaining alcohol into a shallow bowl and briefly dip the sponge biscuits in to soak up the mixture. Put a layer of these in a bowl or deep dish. Layer with the cream mixture until all used up.
• Sprinkle some cocoa powder or grated dark chocolate over the top if you like, to make it look pretty. Stick in the fridge for a couple of hours until it's firmer.
