I like the idea of these puddings as you could prepare them up to the baking stage and then put them in the oven just before you’re ready for dessert. If you don’t like using tinned pears you could poach some fresh pears. I think might actually be really nicer.
Like Mum I have a pretty large collection of cheesecake recipes, but this is the first one I’ve come across that uses Italian Macaroons as a base and pears as a topping. You could use fresh pears in place of the canned ones if you wanted to, but I think you’d need to poach them first to soften them.
