Tonight I made taco soup with bison beef! I've never cooked with it before, apparently it is really really really lean and has more protein than regular cow beef. I noticed that when I was browning it, there was zero grease. I really didn't taste a difference, although any flavor (or lack thereof) may have been masked by the tasty/spicy soup it was stirred into. I didn't tell Andrew (or my sister & her husband who came over) that it wasn't regular beef. Mwahahaha....I'll have to ask them and see if they noticed any difference.
I purchased a pound of it at Health Nut (in Wyndhurst) and it was pricier than regular beef, but worth a shot. It was $9.95/lb. Anyway, I thought it was great and it gets the Hutcheson stamp of approval!
