I’ve been veggie for all my adult life, so I haven’t eaten a traditional lemon mousse for a long long time, but I still occasionally think back to those treat lemon mousse pots from M&S in my childhood! Since Big S is a huge citrus fan I knew it would appeal to her too, but it has been a difficult recipe to develop – the lemon juice almost ‘curdles’ any dairy-free cream and most attempts have led to a thick and over-creamy top above some watery lemon soup at the bottom. Which is not nice.
This recipe on the other hand gives you a billowy, cloud-like lemon mousse which is every bit as aerated as an egg, milk and gelatine based original. Using the the same process as my strawberry soufflé, the aquafaba meringue gives it a light mousse-like texture, the dairy-free cream creates rich creaminess and the lemon gel adds some zingy lemon flavour. It is best eaten on the day it’s made, or the next day (after any longer it will want to separate) but there is no need to hang around before eating it.
As you can see from the following two pictures the texture firms up over time. In the first photo the mousse is about 1 hour post creation and has a light fluffy texture, with the texture of a citrus foam. The second picture shows the mousse the following day and you can see the texture is firmer and more creamy, with a more traditional mousse consistency.
