I need a little help settling a friendly dinner wager between my wife and I. We were prepaing dinner together, and she questioned my use of dry 1/4 measuring cup for adding water to a pan. She said I should be using a liquid measuring cup for all liquid measures because its different then a dry measuring cup. Being of a science background I instantly refuted her claim. She pulled the "I took Home Ec" claim saying something on the line that liquid cup accounts for meniscus, and that spatially they're different. "No way" was my response. I get that a liquid cup is larger then one cup for ease of use, but other then that there are no differences. Please help solve a friendly dinner debate. Thanks.
