This is not really “butter” but have no idea what you would call it…jam maybe but not really..anyway as my husband said …it looks a bit like sump oil (charming!!!) but if you like something a bit different then this is lovely…goes really nicely with cheese and crackers.
Pop it all in a pan and then bring to the boil..turn down to a low boil and leave for about 45 minutes stirring frequently. It should be gloopy (technical word there!) and I hate to say it but dark and looking a bit like sump oil by this time !
Pop it into sterilised jars. Put the lids on a let it cool.
