Crushed pineapple: why 256 g per cup is wrong
King Arthur Baking Ingredient Weight Chart publishes 256 g (9 oz) per US cup of crushed pineapple. This site rejects that figure. The sources it accepts put a cup at 195–237.5 g (6.9–8.4 oz), and it publishes that range rather than a single figure. The reason:
Heavier than the can's full contents. A cup of crushed pineapple with all its juice weighs 243 to 249 g (Dole's label, USDA's juice-pack record, the Food Buying Guide's count with liquid). Draining takes juice out and leaves air between the shreds, so a drained cup weighs less, 195 to 238 g in USDA's measurements. At 1.08 g/mL, 256 g a cup is heavier than the pineapple juice itself, which weighs about 1.05 g/mL (FSANZ: canned pineapple, juice only, 1.05).
