The one I used, years ago, was on a rectangular
metal container of maple syrup and it included
walnuts. I don't THINK it had any flour in it, but
if it did, it was little enough so that the pudding
was never a solid. I.e., not a baked pudding, I
think - it was as liquid as instant chocolate pudding.

I don't know which keywords to Google on without wasting
time - can anyone help? Thanks.
