One of my favourite ways of using my apples is stuffing them and baking them. You'll need an apple per person and a jar of mincemeat for the simple version.
Wash the apples well, I use a soft vegetable brush to ensure they're really clean. Take out the cores; I use an apple corer - you can see how neatly it does it above. Take a sharp knife and score around the centre of each apple - this enables the apples to rise and avoids the mess of exploding apples!
