FAQ

Why is fat-free Thousand Island denser than the regular version?
Removing oil (which is lighter than water at about 0.92 g/ml) and replacing it with sugar-based thickeners and water raises the overall density to 1.082 g/ml, so the fat-free version actually weighs more per cup than the original.
How much does one cup of fat-free Thousand Island dressing weigh?
At 1.082 g/ml, one US cup (237 ml) weighs approximately 256 grams, which is about 19 grams heavier than a cup of water due to the dissolved sugars, tomato solids, and relish particles.
Can I use fat-free Thousand Island as a direct weight substitute for regular Thousand Island?
The density difference means the fat-free version at 1.082 g/ml is heavier per cup than oil-containing versions, so measuring by weight rather than volume ensures accurate recipe results when substituting.
