Sorry if I sounded judgemental earlier, it just had never occurred to me that some people might weigh food after cooking. A bit like the first time you discover that there are people who hang the toilet roll the "other" way round!
I had similar annoyance carb counting yesterday, it was an instant noodle cup that not only gave nutritional info per made up weight, but didn't tell you how much water you added to reach the "fill line" so you couldn't even work it out. As the dry weight was 75g, the maximum carbs are unlikely to be over 65g but it still bugged me.
