I was just wondering how long will the Quincemeat keep for if it is decanted into sterilized jars? I'm wondering how far in advance I can make it before making my mince pies.
Nigella's recipe for Quincemeat (from HOW TO BE A DOMESTIC GODDESS) is very easy to make as the quinces are sliced and roasted and when cool they are mixed with the remaining ingredients. However this means that the complete mixture is not boiled and therefore it does not keep for that long, even if packed into sterilized jars. The Quincemeat is best kept refrigerated and we would suggest that it is used within 10 days of making. The quincemeat can also be frozen in airtight containers for up to 3 months. Defrost overnight in the fridge before using.
Nigella's Star-Topped Mince Pies recipe includes a recipe for a cranberry-studded mincemeat. This mincemeat, if made with port and brandy, can be packed into sterilized jars and will keep for up to one month in a cool, dry place. Pour a little extra brandy on top of each filled jar before putting the lids on as this will help to form a seal over the mincemeat.
