Walnut and Maple Syrup Ice Cream / Walnußeis mit Ahornsirup

Very nice ice cream, though not overwhelmingly so. Actually, I ended up substituting most of the ingredients - pecan nuts for walnuts, sugar beet syrup for maple syrup, and koffie room for evaporated milk - turns out that contrary to what I thought the former was homogenised, sterilised, non-evaporated cream. I found out while making the ice cream (the cream didn't turn stiff when beaten) but otherwise I don't think the difference was noticeable.
