Lime and coconut mousse cake

Two iconic flavours of the tropics, lime and coconut, meet in this recipe. The richness and sweetness of the coconut milk soften the sharp acids of the lime, resulting in a balanced, exotic flavour profile. The neutrality of the sponge lets the character of the cream shine through. This cake is like the first day of a beach holiday: sunny and promising.

Instructions

1

Grate the fragrant green zest of the limes, then squeeze out their juice.

Tip: The zest contains the essential oils, the juice the acids. Both are needed for the full flavour experience.
2

Soak the gelatine in the water for 5 minutes, then heat gently until liquid and transparent. Let it cool until lukewarm.

Tip: If you pour it hot into the cream, the heat will cause the foam to collapse and become runny.
3

Whip the cold double cream with the sugar until stiff.

Tip: Cold equipment (bowl, whisk) helps the stability of the fat crystals, making the foam more durable.
4

While stirring continuously, pour the lime juice, zest, and lukewarm gelatine into the whipped cream. Mix in half of the desiccated coconut as well.

Tip: Add the acidic lime juice slowly so it doesn't curdle the cream proteins.
5

Place the sponge cake base in the tin, pour the cream over it, and sprinkle the top with the remaining coconut.

Tip: You can drizzle a little lime syrup over the sponge to make it moister.
6

Place in the fridge for at least 4 hours to set firmly enough to slice.

Tip: The desiccated coconut absorbs moisture during the resting time, becoming softer.

Recipe FAQ

Can I use coconut cream?
Yes, the flavour will be even more intense. In this case, less sugar might be enough.
What do I do if the gelatine has clumped?
Gently reheat the whole cream (or a part of it) over steam until dissolved, then cool it back down.
