How to measure canned mashed sweet potato
The USDA entry is “Sweet potato, canned, mashed, 1 cup = 255 g”, so the figure is for the canned product. King Arthur Baking’s chart gives 240 grams per cup for mashed sweet potatoes, 15 grams less, and does not say whether they are canned or home-cooked. Both numbers are well above mashed white potatoes at 210 grams per cup on this site. Mashed sweet potato is the heaviest vegetable entry here. Spoon it into the cup, level it and scrape it out, or weigh it. Half a cup is about 128 grams and a quarter cup about 64 grams. Canned pumpkin purée, often used in the same recipes, is 245 grams per cup.
Sources: 255 grams per US cup is the cup weight in USDA FoodData Central (open FDC entry 169305), entry “Sweet potato, canned, mashed, 1 cup = 255 g”. A US cup is about 237 milliliters.
