Creamy Lime Mousse Recipe

This recipe yields a light, airy, and intensely flavorful Creamy Lime Mousse, a refreshing dessert that is both simple to make and elegant to serve. This mousse captures the bright, tangy essence of fresh limes in a smooth and delicate texture, making it a perfect palate cleanser or a light and satisfying sweet treat. The base of the mousse typically involves a combination of lime juice and zest for a concentrated lime flavor, sugar for sweetness, and often a dairy component such as heavy cream or evaporated milk to provide richness and creaminess. Eggs or egg whites are frequently incorporated to give the mousse its light and airy texture, either by whipping them to stiff peaks and folding them into the base or by using them to create a custard that is then lightened. Gelatin or agar-agar may be used as a stabilizing agent to help the mousse set and hold its shape. The preparation usually involves heating the lime juice, zest, and sugar with the stabilizing agent, then whisking in the dairy and any egg components. The mixture is then chilled for several hours to allow it to set into a light and wobbly mousse consistency. Creamy Lime Mousse can be served in individual glasses or bowls and garnished with lime slices, a sprinkle of lime zest, or a dollop of whipped cream for an extra touch of elegance. Its vibrant flavor and smooth texture make it a delightful dessert, especially on a warm day. The image shows a clear glass bowl filled with a pale green, light, and airy mousse.

The texture of Creamy Lime Mousse is light, airy, and incredibly smooth, almost melting in the mouth. It should be delicate and wobbly, yet firm enough to hold a soft shape when spooned.

The flavor profile is dominated by the bright, tangy, and refreshing taste of fresh limes, balanced by a sweet base. The zest adds an aromatic and slightly bitter complexity to the overall flavor.

Creamy Lime Mousse is a light and refreshing dessert that perfectly captures the vibrant and tangy flavor of fresh limes in a smooth and airy texture.

The preparation involves combining lime juice and zest with sugar and a stabilizing agent, incorporating dairy and possibly eggs, and then chilling the mixture until it sets into a light mousse.

Ingredients:

  • ½ cup fresh lime juice (from about 4-6 limes)
  • 2 tablespoons lime zest (from about 2-3 limes)
  • ½ cup granulated sugar
  • 1 packet (about 2 ¼ teaspoons) unflavored gelatin powder OR 1 teaspoon agar-agar powder  
  • ¼ cup cold water (if using gelatin)
  • 1 ½ cups heavy whipping cream, chilled
  • 2 large egg whites (optional, for extra lightness)
  • Pinch of salt (if using egg whites)

Optional for Garnish:

  • Lime slices
  • Fresh lime zest
  • Whipped cream

Equipment:

  • Medium saucepan
  • Whisk
  • Measuring cups and spoons
  • Medium mixing bowls
  • Electric mixer (handheld or stand mixer)
  • Rubber spatula
  • Serving glasses or bowls

Instructions:

  1. Prepare the Lime Base: In a medium saucepan, combine the lime juice, lime zest, and granulated sugar. If using gelatin, sprinkle the gelatin powder over ¼ cup of cold water in a small bowl and let it bloom (sit and soften) for 5-10 minutes. If using agar-agar, add it directly to the lime juice mixture.
  2. Dissolve Stabilizer: Heat the lime juice mixture over low heat, stirring constantly, until the sugar and gelatin (if using) or agar-agar (if using) are completely dissolved. Do not boil the mixture if using gelatin. If using agar-agar, bring the mixture to a gentle simmer and cook for 1-2 minutes, stirring constantly, to activate the agar-agar. Remove the saucepan from the heat and let it cool slightly.
  3. Whip the Cream: In a medium mixing bowl, whip the chilled heavy whipping cream with an electric mixer until stiff peaks form. Set aside.
  4. Whip Egg Whites (Optional): If using egg whites, in a separate clean, dry mixing bowl, beat the egg whites with a pinch of salt until stiff, glossy peaks form.
  5. Combine Mixtures: Gently fold the whipped cream into the cooled lime juice mixture using a rubber spatula until well combined and the mixture is smooth and evenly colored. If using whipped egg whites, gently fold them in as well, in two additions, being careful not to deflate the mixture. This will make the mousse even lighter.
  6. Chill to Set: Divide the mousse evenly among individual serving glasses or bowls. Cover them with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the mousse to fully set.
  7. Garnish and Serve: Before serving, garnish the Creamy Lime Mousse with lime slices, a sprinkle of fresh lime zest, or a dollop of whipped cream, if desired. Serve chilled and enjoy the refreshing flavor.

Enjoy this light and tangy Creamy Lime Mousse! It’s a perfect dessert for any occasion.
