Frequently Asked Questions

How many grams is ⅓ cup of whole milk? ▾

⅓ US Cup of whole milk measured poured liquid weighs 80 grams (2.82 ounces).

Why does 1 cup of whole milk weigh 240g while water weighs 236.6g? ▾

Milk contains dissolved sugars (lactose), proteins (casein, whey), and emulsified fat globules, giving it a higher specific gravity (~1.03).

Does scalded milk make bread dough rise better? ▾

Yes, heating milk to 180°F denatures whey proteins that can otherwise weaken the gluten structure in yeast breads.
