Chop the almonds and toast them in a little butter and sugar, then let them cool.
Meanwhile, whip the cream. Chop the meringue and chocolate and add to the cream. Add the cooled almonds. Fold everything in well, then fill the mixture into molds and freeze for at least 4 hours (preferably overnight).
Thaw the berries and strain 3/4 of them through a sieve.
Arrange a mirror of the berry puree in the middle of the plates. Turn the ice cream tartlets out of the molds, place them in the middle and serve decorated with the remaining berries, powdered sugar and lemon balm or mint.
