All-Purpose Flour (Best Option)
1 tablespoon per 1 cup of liquidAll-purpose flour works well as a substitute due to its balanced protein and starch content, which helps in thickening the risotto gently while preserving the creamy texture. The starch gelatinizes during cooking, contributing to the desired mouthfeel.
When using all-purpose flour, it is best to mix it with a small amount of cold liquid before adding to the hot risotto to avoid lumps. Stir continuously to ensure even thickening.
Compared to cake flour, all-purpose flour may produce a slightly thicker and less tender texture, but this difference is subtle and usually acceptable in risotto.
