Why Weigh Corn Syrup in Grams?
When a recipe calls for 2½ cups of corn syrup, using a kitchen scale to measure exactly 820 grams will give you far more consistent results than volume measurement alone. This is because corn syrup can be packed, sifted, or scooped differently each time, leading to weight variations of up to 20%.
How to Measure Corn Syrup by Weight
Place your mixing bowl on a digital kitchen scale and press "tare" to zero it out. Then add corn syrup until the scale reads 820g. This method is faster than measuring cups and eliminates the guesswork entirely.
Also Known As
Corn Syrup is sometimes referred to as light corn syrup, dark corn syrup. The same conversion of 328g per cup applies regardless of the name used.
