This is a really easy recipe and it is easily customized to your own tastes. My mother made this up for me when I was little. I loved these books about little mice celebrating the seasons and in one book they made a tart much like this. You will need:
Dough for a 1 shell pie
Blackberry Jam (or whatever jam you like but I suggest seedless and whole fruit not jelly)
3 large apples (any variety you prefer I had Golden Delicious on hand)
1 tablespoon lemon juice
1 tablespoon cinnamon and sugar mixed together
That’s it folks really short list of ingredients isn’t it. Now turn your oven to 400 degrees and roll your dough out. I rolled mine into a rough square because I do not own a round sheet pan but you can make it whatever shape you want. Crimp the sides a little like a pie so that all of your jam does not drip off. Some of it will anyhow so you will want to make the dough slightly smaller than the pan to give room for this. Sprinkle the top with the cinnamon and sugar.
Scoop your jam into a microwavable container, I used a glass measuring cup, and warm it until it can be poured. Pour it over your apples and use a utensil to even the jam out over the apples. Place it in the oven for 25 to 30 minutes or until the crust is browned and the apples are tender. This is great warm for breakfast or could be cooled down and easily packed in a lunch or for a picnic. It would be perfectly acceptable for a desert too.
