The simplicity of this vegan and gluten-free apple blackberry crumble tart challenges traditional notions of complex baking techniques by demonstrating that delicious desserts do not always require intricate steps or elaborate processes. The one-bowl dough mixing method eliminates time-consuming kneading and rolling typically associated with pie crusts while still achieving a tender yet sturdy base for the tart. Pressing it into shape with fingers rather than meticulously shaping it with precision showcases how easy it is to create an aesthetically pleasing dessert without advanced pastry skills. This approach highlights that simplicity in ingredients and methods can yield beautiful results contrary to conventional beliefs about needing sophisticated techniques for successful baking outcomes.
