For the mustard, you can use an "old-fashioned" mustard, the seeds adding a little extra taste and texture.

Usually to make fruit jellies or (fruit "paste"), it's like jam but you need to cook fruit pulp and sugar much longer. Unfortunately, this long cooking is bad for both vitamins and flavour. In this recipe we use a special jam gelling agent, to reduce cooking time as much as possible .
