Sugarfree lime mousse

This time I went for an up and coming summer recipe. Something fresh, sweet but also sour at the same time: the sugarfree lime mousse!

Preparation time

15 mins preparation

Print this recipe


For 6 servings
  • 200 g mascarpone
  • 50 g Zùsto
  • 200 ml heavy cream
  • 2 limes (juice + zest)


  • 2 mixing bowls
  • 6 glasses to serve the mousse in
  • Grater
  • Piping bag (optional). It just allows you to squirt the mousse neatly into the glasses.

Preparation method

  1. Pour the cream into a mixing bowl and whip up lightly. Spoonful by spoonful, add the Zùsto. Keep going until the whipped cream is lumpy (don’t whip it up completely yet).
  2. Squeeze the 2 limes, keeping the juice aside. Grate the peel for the zest.
  3. In another mixing bowl, pour the mascarpone together with the juice from the 2 limes. Whip the mascarpone loosely with the juice.
  4. Add the mascarpone batter to the cream and mix again briefly until you have a smooth batter.
  5. Spoon the batter into glasses (or, using a piping bag, pipe the mousse into the glasses, which works a little better) and top with the zest.
  6. Store in the fridge.

About Yasmine Marchal

Hi, I’m Yasmine from the pastry blog Tartes Yaya. As well as running my blog, I work full time as an IT project manager. Baking is my creative outlet, but I also enjoy sports (jogging, hiking, aerial dance and horse riding).

I’m mum to an 8 year old boy, Ilyas, and a 6 year old girl, Fatou. In August 2018, Ilyas was diagnosed with type 1 diabetes (an autoimmune disease that is not caused by eating too much sugar… just to clarify that! ;)).Even though a type 1 diabetic can eat whatever they want and don’t have to follow a special diet, their body has greater difficulty in processing real sugars because the body is not able to produce insulin itself or manage insulin spikes properly.

My son’s diabetes led me to discover Zùsto and since then, Zùsto has been my favourite sugar substitute!
