What defines a mousse?

Mousse is a creamy dessert that translates as ‘foam’ in French. It can be both thick and rich or light and airy.

It’s most commonly a sweet dish but can also be savoury.

In the recipe below, the mousse has a light and refreshing consistency. The fresh strawberries give off an amplified fruity flavour and the rich sponge base layer balances it out well.

What milk should I use for the sponge layer?

In this recipe, we use dairy free milk to create a vegan version of buttermilk. Just add cider vinegar to the milk and allow it to ‘curdle.’

There are lots of different dairy milk alternatives out there such as almond, soy, cashew and oat milk.

Soy milk contains the most proteins out of all the milk alternatives, so it’s great for baking. Because cakes need a lot of structure, the protein is vital in helping to create the gluten that holds the cake together.

It has a mild taste so is easy to flavour with vanilla, for example. Baking with soy milk also means the cake will brown well.

What is agar?

Agar is an alternative to gelatine.

It has a similar jelly-like texture and has little taste or colour. It helps to thicken and texturise sauces and baked products.

It’s versatile and great for all sorts of recipes that would normally need a thickening agent like gelatine.
