The taste and mouth-feel will fool even the most squeamish people (assuming you cut the meat off the bones). Grind up breast meat 70/30 with bacon (or more 'cuz *bacon*) to make a burger patty. It's not a total substitute for hamburger, but we can't all have cows roaming around. I don't know if *every* type of duck tastes the same, but your meat varieties like Pekin and Cayuga work just fine.
