Oh, mincemeat, is a rich fruit mix, rather like a fruit cake mix, but instead of adding eggs, butter and flour, it is mixed with suet (a grated fat), sugar and spices - and lots of brandy - then stored in a jar. It is used to make mince pies.
Mince pies are made in what, in the USA, would be shallow muffin pans. The pan is lined with pastry then 2/3 filled with mincemeat and a pastry cover is put over it and the join sealed. These will be baked in the oven for around 20/30 minutes and be served warm. Usually with a scattering of icing sugar over them.
We also have Christmas pudding, made from - guess what - dried fruit, spices, eggs, flour, suet and - plenty of brandy- The puddings are put on pudding basins and steamed on the hob for hours or put in a microwave for minutes.
Yes, we go big on dried fruit - and brandy - at Christmas, but fewer and fewer people eat all these delicacies these days as they are very rich and there are so many alternatives, like panettone from Italy, stollen from Germany and Bouche du Noel (Yule log) from France instead of the cake, any light sweet instead of the pudding.
But everyone (well, nearly everyone) loves mince pies.
