WTSIM Plum and Apple Crumble

We are yo-yo-ing between summer and autumn here in the Cape, though it's almost unheard of to even have a wisp of autumn in February. Usually we are gasping from the heat of a week of 40 degrees, suriving only by constant immersion in the pool and living off salads and braais... bread-baking a trial to undertake only when the relative cool of evening brings the temperature down a notch or two.
