Place cornelian cherries, sugar, salt and vegetable stock in a saucepan, bring to the boil and simmer for approx. 10 minutes, stirring occasionally, until the cornelian cherries soften and some of the flesh separates from the stone.
Pass the cornelian cherry mixture through a sieve to remove the stones.
Peel garlic and cut it into coarse pieces.
Place the fine cornelian cherry mixture, the garlic pieces, mint leaves, chilli pepper, coriander powder, vegetable oil and white wine vinegar in a blender and mix until smooth.
Pour the cornelian cherry sauce into a clean container, season again with spices, sugar and salt if necessary and serve.
