For my birthday this year instead of a cake I made this lemon mousse with crushed biscuits after A. spotted a tin of condensed milk in the cupboard (he loves the stuff).
It's not that cold yet so I thought I'd share the recipe with you in case you want to try it. This lemon mousse is very quick and easy to make but I found it's best to leave to set in the fridge overnight or if you think that's too long to wait to have a taste, you can make it as early as possible in the morning and then leave it to set for at least 4 to 5 hours.
Lemon mousse with crushed biscuits
1 tin condensed milk
100ml lemon juice
200g rich tea biscuits crushed *
500ml whipping cream
In a bowl mix the condensed milk with the lemon juice. Let it rest in the fridge for 30 minutes.
Whisk the whipping cream until it thickens. Add to the condensed milk mixture and fold gently.
Choose a deep bowl and alternate layers of the cream with the crushed biscuits. The last layer should be crushed biscuits. Keep in the fridge until set and cool enough to serve (preferably overnight).
* If you buy cereal clusters you'll usually have lots of crumbs left in the packet, I used mine together with the crushed biscuits for the top layer of the mousse to add it some crunch. Also, I think crushed ginger biscuits might work very well with this mousse.
