This is the rice for making authentic Spanish paella. There are a few other varieties that work well in paella, but Bomba is top of the line. It's shorter grain rice, and though it resembles Italian arborio in shape, it behaves much differently. It can absorb 3 times its volume in liquid yet still retain its toothy texture. When using Bomba, you'll need 3 cups of liquid for each 1 cup of rice. Bomba does cost more than other rice, but if you want to make paella the Spanish way, this is the way to go.
