In a medium-sized bowl, fold together the filling ingredients and layer into the bottom of a small cast iron pan (around 8”)
In a separate medium-sized bowl, mix together the crumble ingredients, until incorporated. Crumble the crumble topping into the filling. Cover the cast iron with aluminum foil
Preheat Forno Venetzia oven to 350 °F, using 1-2 small to medium logs. Once at temperature, move logs to one of the rear corners to maintain high heat. Alternatively, if using the oven for high temperature cooking, utilize the natural cool down of the oven for cooking the crumble
Place the cast iron pan into the Forno Venetzia oven, opposite the the burning logs
Allow the crumble to cook while covered for 15 minutes at around 350 °F. After 15 minutes, uncover and cook for another 15 minutes.
Rotate the pan as necessary to ensure even browning to the topping. Crumble is done when the filling begins to bubble out the sides and the crumble is brown
