Plum Slice with Blackcurrant Sauce

2 cups flour (white wheat, whole wheat pastry, or oat flour)
1/4 cup honey
1/2 cup butter

1/4 cup flour (as above)
1/4 cup sugar
1 tsp. honey
1 tsp. baking powder
1 1/2 cups pureed plums
4 eggs
1/2 tsp. arrowroot powder

Preheat oven to 350 F. Grease a 9x13" cake pan.

Cut honey and butter into the flour until there is no more fine powder and it can be pressed together into dough. Press dough evenly into the bottom of the pan.  Bake for 15 minutes, or until lightly browned.

When the crust is almost done baking, beat together the flour, sugar, honey, baking powder, plums, eggs, and arrowroot.

Pour the filling over the hot crust, and bake for 25 more minutes.

Serve with blackcurrant sauce.
