Step-by-Step Preparation Guide
Creating this crisp is straightforward and rewarding. From preparing the fruit filling to assembling and baking, each step brings you closer to a delicious homemade dessert. Follow these instructions to ensure your crisp turns out perfectly every time.
Preparing the Fruit Filling
Begin by washing and slicing your peaches and rhubarb. In a large bowl, combine the fruits with sugar and a bit of lemon juice to enhance the flavors. Let the mixture sit for a few minutes to allow the juices to meld, creating a rich and flavorful filling.
Making the Crisp Topping
In a separate bowl, combine oats, flour, brown sugar, and butter. Mix until the mixture resembles coarse crumbs. This combination will form the crunchy topping for your crisp, adding texture and sweetness to the dessert.
Assembling and Baking
Preheat your oven to 350°F. In a greased baking dish, spread the fruit filling evenly, then sprinkle the crisp topping over the fruits. Bake for 45-50 minutes, or until the topping is golden brown and the fruit filling is bubbling. Allow the crisp to cool slightly before serving.
