Measuring 100g of granulated sugar without a scale
No scale? 100 g of granulated sugar is about ½ cup (0.5 cups), or roughly 8 tablespoons using standard US measuring cups and spoons. Spoon it in and level off the top instead of scooping, which packs in extra.
100 g of granulated sugar is half a US cup and a genuinely versatile baking quantity. It sweetens a small-batch cookie dough of roughly a dozen, the sponge for a 6-inch single-layer cake, or a modest pot of lemon curd. A useful mental anchor: 100 g is half of a typical 200 g cup and almost exactly the sugar weight that balances 100 g of butter in a simple creamed mixture, which is why so many beginner recipes pair the two one-to-one.
