In the container of a blender, process cilantro, 1 cup water, broth, green onion, pepper sauce, salt, and garlic until smooth.
In a medium saucepan, melt butter over medium heat. Add rice; cook, stirring frequently, until toasted, about 4 minutes. Stir in cilantro mixture. Bring to a boil over medium-high heat, stirring occasionally. Cover, reduce heat to low, and cook until liquid is absorbed, about 15 minutes. Remove from heat. Let stand for 5 minutes. Uncover; add lime zest, and fluff rice with a fork.
Notes
*We used Slap Ya Mama Jalapeño Pepper Sauce.
