Tuna Patties with… Short Grain Brown Rice Beth Hopping Melanie Uchima Joann Barayuga +

Our Purpose To develop an acceptable tuna patty using short grain brown rice

Image obtained 10/26/08 from Short Grain Brown Rice  Brown rice is in the unmilled form with the bran and germ layers still present.  The extra layers increase cooking time and give the rice a chewy texture and nutty flavor.  Short grain rice is more sticky and clingy than the longer grain varieties.
