Refreshing Lemon Mousse

Use only the yellow part of the peel; the white pith underneath can make it bitter.

Lemons are easier to juice at room temperature.

For an extra-smooth cream, whisk vigorously for a short time until the sugar is fully dissolved.

To avoid lumps, first stir 2–3 tbsp of the cream into the dissolved gelatin, then quickly return everything to the remaining cream.

If you want it to set faster, chill the glasses briefly before filling.

Suitable garnishes include lemon zest, berries or a few mint leaves.
