Using a pairing knife or an apple core device, cut the core out of your apples, making sure to get the seeds and all of the tuff apple bits out.
Chop your raisins roughly.
Mix together brown sugar, cinnamon and raisins in a bowl.
Stuff the middle of the apple with your raisin mix.
Place the apples into a baking dish and add a dollop of butter to the top of each one.
Put the apples in a 190 degree Celsius, pre-heated oven.
Add boiling water to the base of the baking dish, enough to cover the bottom, and bake for 30 to 45 minutes
