Preheat the oven to 400 degrees.
In a large mixing bowl, toss rhubarb, sugars, salt, lemon juice, and almond extract. Set aside.
In another bowl blend dry ingredients – flour, 2 tablespoons sugar, and baking powder. Cut in the shortening and butter. Add the milk and egg and stir to create the cobbler dough.
Grease or butter a 9×9 baking dish and pour rhubarb mixture onto the bottom – use a spatula to scoop out all the liquid. Rally the kids to come and, with clean hands, show them how to scoop blobs of cobbler dough and drop it on top of the rhubarb.
Bake for 30 minutes or until bubbly and golden.
