Lemon Grass & Kaffir Lemon Mousse Cake

This cake really strikes me, just like love at the first sight. Why?…… a very asian flavour yet so western. Looks simple too but the flavour will burst in your mouth once you have a bit of it, really explosive. Lastly the ingredients are easily obtain and available fresh. Well I am talking about this lemon grass and kaffir lime mousse cake.

I stumbled upon and yet again this recipe when I was glancing through Anita & Sam’s Everday Treats. They created this recipe when they visited a shop called ‘Spice’ in Thailand. They had used the dry and powdered lemon grass and kaffir lime but I modified a bit, instead of using dried powder, I used fresh ones. The verdict…. incredible and unique, truely asian. For this cake I opted out using any food colouring and the cake turn out to be stunning bright and attractive yellow.

Prepare a 9inch cake mould and wrap it with aluminuim foil.
Prepare a digestive biscuit cake base.
