Measuring tips

  • Weigh in grams on a kitchen scale for the most accurate result, and set the scale to zero (tare) with the bowl on it.
  • This site uses the US cup of 236.6 ml. A metric cup is 250 ml, so recipes from the UK, Australia or New Zealand can differ.
  • Check whether the recipe means the ingredient sifted, packed, melted or cooked, because that changes the weight per cup.
