Or could I just use maple syrup?

I've checked two supermarkets and they didn't have it (assuming the
only place to look was in the baking supplies aisle, with all the
other bottled flavorings). I have a third to check, plus my local
health food co-op, but I doubt it's there either! Where do YOU get it?

It's for the "bird's-nest pudding" recipe in the "Little House
Cookbook." The recipe includes six apples.

BTW, the author, Barbara Walker, turned 80 this year!
