Instructions
In a medium sized mixing bowl, combine the 1 1/3 cup diced, fresh strawberries1 1/3 cup fresh raspberries and 1 1/3 cup diced fresh or frozen rhubarb* (see tips if using frozen rhubarb). Add in the 1 cup granulated sugar, 1/2- 1 Tablespoons cornstarch* (see tips if using frozen rhubarb), 1 teaspoon fresh lemon zest and 1/2 teaspoon ground nutmeg Stir until the fruit is completely coated.
Place fruit in an even layer in a greased 8" or 9 " baking dish.
In a separate mixing bowl, stir together the 3/4 cup brown sugar,3/4 cup all-purpose flour, 3/4 cup old-fashioned oats, 1/2 teaspoon baking soda and 1/4 teaspoon salt. Stir in 6 Tablespoons unsalted butter, melted and mix until combined.
Sprinkle the oatmeal topping evenly over the fruit. Place the baking dish on a sheet pan to catch any fruit juice that bubbles over while baking. Bake @ 350°F 30-35 minutes, until bubbly around edges and crumble topping begins to crisp. Serve warm.
Notes
If using frozen rhubarb, thaw completely and drain before using.
Do not decrease the sugar with the fruit; rhubarb is very tart and needs sugar to balance it out.
Store baked crisp covered for up to 72 hours in the refrigerator.
