For this recipe I'm using a round pan about 26-28 cm in diameter. If yours is much bigger or much smaller, just adjust the amounts a bit.
So, line the pan with parchment paper and bring the paper edges up to cover the interior sides of the pan. Notice that I have a removable bottom pan and I could have let the sides uncovered but, this way, the juice from the fruit would be released in the oven, making unpleasant smoke.
