The best way to achieve frugality is for one to learn how to make as many meals as possible using the humble potato. This has to be my personal favourite, thus far. The hasselback potato is a Swedish version of the baked potato, though due to the way it’s sliced it also tastes a little like a chip (fries). Although it pains me to lower my vocabulary to such base and vile terms, this is a really sexy way to prepare a potato – let it never be said that potatoes are boring. How naughty and un-British was that?
