I finally stopped eyeballing rice portions after my roommate said my "cup" was a coffee mug
She watched me pour 3 mugs of rice into the pot for two people in our Austin apartment and just said "that's why you always have leftovers, those mugs hold 12 oz not 8," so now I actually use the one real measuring cup we own and my grocery bill dropped about $15 a month, has anyone else been cooking for years with a completely fake sense of what a portion is?
