Important Note about Salt: Not all salts are made equal and cannot be substituted 1:1. If you are substituting table salt for kosher salt, you will need to cut the amount called for in the recipe by at least half.
Orzo tends to absorb a lot of broth, so you can either cook it separately and store it that way, or add a little water or broth before reheating.
I prefer adding a splash of water and pinch more of salt before reheating on the stovetop— it tastes just as delicious!
