Instructions
First make the pastry eg this recipe, roll it out and fill the base or use a ready-made pastry shell. Chill until ready to fill.
Preheat oven to 375F/180C.
Peel, core and slice the apples relatively thinly and put them in a bowl, tossing with a few drops of lemon juice as you cut the rest. Continue until all are cut. Sprinkle over the cinnamon and sugar and toss so all slices are coated.
Lay the apples in the pastry shell as you prefer, such as the rose-like shape I made working from the outside in, putting a layer around the outside then circling round on top. It's not too important how they look as you won't see, just try to get it relatively flat.
Whizz together the walnut pieces and oats in the food processor until you get relatively fine crumbs. Add the flour,sugar and the butter in small chunks and pulse until combined. Sprinkle the mixture evenly over the apples.
Bake the tart for approx 1 hour until starting to brown and apples are tender.
Can be eaten warm or room temperature and it's good with cream or ice cream (my favorite is warm with ice cream).
