• Make sure you use a bun tray as opposed to a muffin tin. The latter is much deeper and although prefect for muffins & cupcakes, it is too deep for mince pies. If you don’t already have one, I highly recommend purchasing one, not only for this recipe but for Jam Tarts, Pineapple Tarts and Strawberry Tarts.• A jar of mincemeat is fine as it is but I find pimping it up a little with some fresh apple and dried cranberries makes it a bit more luxurious. You can add whatever dried/fresh fruit that is to your own taste, or just use it straight from the jar. These are your mince pies, so you do you.• For me, adding a little orange zest to the crumble mixture is non-negotiable… However, it is technically optional. If you come to make these and don’t have an orange to hand, you can go ahead and make them without. The crumble without it is still delicious. You could always try replacing the orange zest with a little lemon zest, or even some ground cinnamon instead.• When adding your crumble to the tops, it is a bit messy – there’s not really away around this. One thing that can help is adding a spoonful of crumble to the tops of each pie, lightly pressing it down a little, before adding the rest of the topping on top.
