When microwaves first appeared on the scene we were told you could cook anything in them and I think this recipe dates back to that time. I now find the microwave indispensible, but use it mainly as a tool to cook vegetables, melt butter or chocolate, defrost meat and to make white sauces. I found that the traditional oven was better for casseroles, roasts and baking in general, but there’s no denying this recipe would cook more quickly this way and could be worth trying.
