As the crumble baked, the kitchen filled with the most heavenly aroma of warm fruit and buttery goodness. I remember pulling it out of the oven, bubbling at the edges, the crumble topping just the right shade of golden brown. One spoonful and I was hooked. The tartness of the fruit against the sweet, crunchy topping was absolute perfection.
