in case you were thinking of mixing types:
Arborio rice and sushi rice are similar in shape and size, and both have a relatively high amount of the starch amylopectin, but Arborio rice isn’t a great choice for Asian dishes because of a defect called “chalk.” During maturation, the starch structures at the core of an Arborio grain deform, making for a firm, toothy center when cooked. While this trait is great for risotto—it gives the dish its signature al dente texture—it’s less than ideal for sushi or for a rice to accompany Asian dishes. Conversely, we’ve tried making risotto with sushi rice. Tasters reported that the resulting risotto was creamy, but “it wasn’t risotto” because the grains lacked the quintessential al dente bite of Arborio rice. The bottom line? Arborio rice and sushi rice are not interchangeable in recipes.
