For the jam, boil up frozen fruits, jam sugar, vanilla sugar and lemon juice in a large pot while stirring. Boil for about 4 minutes while stirring continuously. Immediately fill up to the brim into clean twist-off jars (empty gherkin or jam jars that have been boiled off for about 1 minute beforehand).
Seal and place on the lid for about 5 minutes. Turn over again and let it cool down.
Preheat the oven for the scones (electric oven: 200 °C/circulating air: 180 °C/gas: see manufacturer). Line a tray with baking paper. Prepare all ingredients weighed and cut. Knead the dough and form into scones.
Bake in a hot oven for about 12 minutes. Remove and let cool on the cake rack.
For the cream, stir orange juice, clotted cream and vanilla sugar with whisks until smooth. Cut the scones in half horizontally. Spread the undersides with approx. 1 tbsp. cream and jam each. Place the topsides on top.
Rest Jam keeps dark and cool stored 3-6 months.
