This is a bit before my time, but I have vague nursery memories of a friend of my grandmother's making a version of this, which she would serve with a warm sauce made of pineapple juice thickened with - I imagine - cornflour. That I can do without, but I am still of the mind that it is perfectly all right to make this with canned pineapple rings. I feel it is slightly bad sport to start peeling and slicing your own pineapple.
Anyway, canned pineapple is just fine, though I advise going for the one in its own juice rather than in syrup, and I add some of the juice to the sponge, too. This seems to make it light and fluffy.
