Drain the apricots, mash them, bring to the boil. Mix starch and liqueur until smooth and stir into the puree. Bring to the boil again. Cool down
Soak the gelatine in cold water. Mix yoghurt, sugar, peel and juice. Squeeze out the gelatine, dissolve at low heat. Stir in 3 tbsp. yoghurt, mix with the rest of the yoghurt. Cool until the cream begins to gel
Whip the cream until stiff and fold into the yoghurt cream. Stir about 1/3 into the apricot puree
Pour the yoghurt and apricot cream into 4 dessert glasses at the same time, creating a swirl or marble effect. Or pour both creams alternately by the spoonful. Chill for at least 4 hours. Strawberry and apricot skewers taste great with it
The yoghurt mousse also works with other fruits (fresh, frozen or canned). It tastes delicious with nectarines or raspberries
