How do I scale the original portion?

Start with 120 g per 1 cup. Multiply that gram amount by the requested number of source portions. The generated amount table uses the same calculation as the converter; displayed results are rounded only at the end.

Can I convert milliliters of all-purpose flour to grams here?

No independently verified density is available for this ingredient in this release. Cup/spoon reference weights cannot establish one without a verified source cup volume. Volume-to-volume and grams-to-ounces conversions still work.

Q: Which preparation does this all-purpose flour reference cover?

All-purpose flour; fluff, spoon, and level. Fluff the flour, spoon it into the cup, and level the top with a straight edge. The selected reference follows King Arthur’s measuring method; a densely filled cup can contain more flour.

Use ingredient estimates where supported, or convert volume and mass units. Check cooking measurement conventions.
