I have no idea about the stupid potato, I ate the blasted thing anyways in the end as I had been looking forward to the meal I was making, and frankly, I had a light lunch and was hungry!
Its not like I eat potato very often, it just boggled me how vastl different it was, the SP entries are rubbish... the US ideas of small/medium/large are way off our standards... I weighed an orange before, the weight calories for what we would call a large, where the same as the calories listed for a small one.
Thats why I prefer to do everything by weight! 1798 days ago
