Glutinous Rice Flour: Sweet Rice Flour and Its Chewy Texture
Glutinous rice flour is milled sticky rice.

Glutinous rice flour is milled sticky rice. It is also sold as sweet rice flour, and is used where a cooked dough or batter needs the characteristic cohesive texture of that rice.
Glutinous describes stickiness, not the presence of wheat gluten. Equally, sweet rice flour can be a plain rice product without added sugar. The ingredient list answers that question more reliably than the English name alone.
Why ordinary rice flour is different
Both can be pale powders, but their cooked behaviour differs. Replacing glutinous rice flour with ordinary rice flour can remove the chew a sweet or dumpling is built around. Replacing ordinary rice flour with sweet rice flour can change a batter or baked good in the other direction.
Bob's Red Mill explicitly cautions that its white and sweet white rice flours are not necessarily interchangeable. Treat the named flour as part of the recipe's structure.
Glutinous rice flour is a category
Japanese mochiko and shiratamako both belong to the glutinous-rice-flour family, but their processing and handling differ. Products made for other food traditions may use different rice or milling methods.
If a recipe identifies a particular product or national style, that detail can matter. A broad label does not prove that every bag will accept the same water quantity or produce the same dough.
Using it beyond sweets
Sweet rice flour also appears in gluten-free baking and thickening applications. It may be used alongside other flours rather than replacing all of them. Follow the formula's quantities and cooking method instead of assuming that an ingredient good at binding must be better in unlimited amounts.
For a first attempt, select a recipe written for the flour available locally. A small batch lets you assess the product’s texture before committing it to a larger preparation.
