This Low FODMAP Rhubarb Cheesecake Tart
For the Crust: Position rack in middle of oven. Preheat oven to 375°F/190°. Generously coat the inside of a 10-inch (25 cm) fluted, loose-bottom tart pan with nonstick spray; set aside.
Roll out prepared and chilled tart crust between pieces of lightly floured parchment paper to about ¼-inch thickness (6 mm) and fit into prepared tart pan, trimming edges flush with top of pan. Pierce bottom of tart all over with a fork.
Bake the crust for about 15 to 20 minutes or until just beginning to color. If any crust bubbles up, simply press back down with the back of a fork. Remove from oven. Reduce oven temperature to 350°F/180°. Chill crust on cooling rack until barely warm.
For the Rhubarb and Cheesecake Fillings: While the crust is baking, prepare the fillings.
For the Streusel: Melt butter in wide skillet or pan over medium heat until golden, stirring often, about 5 minutes. Do not let it burn. You will know it is browned enough when it has darkened a little and smells almost nutty. Remove from heat and stir in almonds, sugar, and cinnamon until combined. Stir in flour until moist clumps form.
