Frequently Asked Questions
Why do cup measurements differ by ingredient?▼
Volume measures space occupied; weight measures mass. Different ingredients have different densities. 1 cup of flour weighs ~125g but 1 cup of butter weighs ~227g. This is why weight-based recipes (using grams) are more precise than volume-based ones, especially for baking where ratios matter.
Is a US cup the same as an Australian or UK cup?▼
No — a US cup = 236.6ml. An Australian cup = 250ml (metric cup). A UK cup = 284ml (imperial). Most modern recipes use the US or metric cup. The difference matters for baking: 1 US cup of flour ≈ 125g vs 1 metric cup ≈ 132g. Always check which cup size your recipe uses.
How do I measure flour correctly?▼
The most accurate method: spoon flour into the measuring cup and level off with a straight edge (the 'spoon and level' method). Scooping directly packs flour, adding 20–30% more than intended. Weight is most reliable: 1 cup = 120–130g depending on the recipe's intended density.
What is a 'stick' of butter in metric?▼
1 US butter stick = ½ cup = 8 tablespoons = 4 oz = 113g. Recipes using 'sticks' are US-specific. For metric countries: ½ cup butter ≈ 113g (not 125g — butter is denser than water). 1 tablespoon butter = 14g.
