For this not-very-photogenic sausage casserole I stuck to the recipe, just halving the quantities and adding a couple of turnips that I had lying in the veg drawer. After all, sausage, apples, potatoes and 3 kinds of mustard in a creamy sauce is just about as good as cold weather food gets, isn't it?
It was seriously delicious. The Bramleys disappear into it completely to thicken the sauce and add a bit of sharpness, so if you have a family who doesn't like fruit with meat, don't tell them and they won't know. Lovely. And re-heated very well, so it's quite a good one to make in advance when you know you won't have much time and will want something tasty to come home to.
