I've made Delia's homemade mincemeat (for the first time) this year. I made it a couple of weeks ago and made the first batch of mince pies today. Rather than put a lid on I put a pastry star shape on the top but the mincemeat round the edges has burned - I think specifically the raisins or sultanas. I've never had this problem with shop bought mincemeat. Does anyone have any suggestions for how to get round this or will I just have to make mince pies with full lids?
