Here are some data from the now out of print "Average Weight of a Meassured Cup of Various Foods", Home Economics Research Report No. 41, Agricultural Research Service, US Dept. of Agriculture.
For 1 cup (U.S.) in terms of mass (in grams): barley flour, unsifted, spooned 102 yellow corn flour, unsifted, spooned 117 cornmeal, yellow, degerminated 151 cornmeal, white, degerminated 140 rye, dark, unstirred, spooned 128 rye, light, unstirred, spooned 101 wheat, all purpose, unsifted, spooned 126 wheat, all purpose, sifted, spooned 116 wheat, bread, unsifted, spooned 123 wheat, bread, sifted, spooned 117 wheat, cake, unsifted, spooned 111 wheat, cake, sifted, spooned 99 sugar, brown, packed 211 cornstarch 125 sugar, confectioner's, unsifted 113 sugar, confectioner's, sifted 95 sugar, granulated 196 molasses 309 margerine 225 shortening, hydrogenated 187 oil, cooking 209 yeast, active, dry 142 Data is often available for items in this handbook to indicate number of samples and standard deviations, but I have obviously not included that here. I hope that this is helpful to kitchen commandos who do it right --- in metric. Jim On Tuesday 2004 February 03 22:39, John S.
