Put the rusks in a freezer bag and crush them finely with a cake roll. Melt the fat and mix with diabetic sweetness and rusk crumbs. Line a box form (25 cm long) with foil so that it protrudes over the edge. Pour the crumb mixture into the box mould and press firmly. Put it in a cold place. Soak gelatine in cold water. Mix quark and yoghurt with lemon juice and zest, season to taste with sweetener. Squeeze the gelatine, dissolve carefully. First mix 2 tablespoons of the quark mixture with gelatine, then stir into the remaining cream. Spread evenly on the base. Chill for approx. 2 hours
Carefully lift the cake out of the tin with the help of the foil and cut it into 8 pieces. Cover the slices with grapes. Melt apricot jam at low heat, pass through a sieve and drizzle over the grapes
Tip: Prepare the base from 150 g rusks, 120 g fat, 1 tablespoon sugar and 1 packet of vanillin sugar. For the cream, use mascarpone instead of low-fat curd cheese and sweeten the mixture with 3 tablespoons of sugar
