Heat the purees with the tangerine concentrate (no hotter than 60°C due to loss of flavour).
Mix the cooked Vegantop with the chocolate, cocoa butter and melted purée.
Bring to the boil with a mix of the sugar and two pectins until well dissolved.
Cook for a few minutes, just like jam.
Blend well with the hand blender until a smooth emulsion forms.
Portion into interior moulds of 20 to 22 g each.
Freeze.
