Are you looking for a butterscotch meringue pie (which is common in Nova Scotia), this one is similar to how one my housemates when I was in grad school in NB made hers (there are even instructions for baking it in the microwave). I watched her make it a couple of times, but I didn't really care for it, so didn't ask for the recipe.
