OK, if you’re a person who doesn’t use dishwashers because you thoroughly believe you’re more efficient (er, see previous link!), please do not buy little Yoplait containers. There are about 40 ridges in them where it’s nigh-on impossible to get the yogurt remains out. They were almost all either wet or moldy or not fully cleaned. Pick a tiny yogurt container w/o ridges, esp on top (though again, it’s not anyone’s individual fault).
