I made a quick apple tart for a guest. I put it in the oven when we started eating dinner, and it was cooked when we finished the main dish. To make it, I used ready-made pastry cut in a square, on parchment paper. I pre-heated the oven to 350° F/180° C. I used two apples, which I peeled and then sliced thinly with a grater. I mixed them with a little sugar and cinnamon, then piled them high on the pastry sheet and wrapped the edges around it.
Once the pastry was a nice golden brown, I turned off the oven and let it sit. Meanwhile, I made the caramel sauce. To make it, I melted about half a cup of sugar in a saucepan, and let it cook to a golden brown. I then gradually added in oat cream until it was the desired consistency. Adding the cream keeps the caramel from becoming a sticky hazard to teeth, or from solidifying. I poured the caramel sauce over the tart and served it.
