My wife renders all our bear fat each year. She also renders cow fat into tallow. The two are pure white, taste neutral and the same consistency. Lard would be different, beef tallow would be the closest in my opinion. I boil skulls down with the brain in to make bone broth also. Just finished some elk and the fat skimmed off the top after everything cooled 48 hours later looks and tastes the same as tallow or rendered bear fat. If you have access to ruminants heads, this could be an option as well. As for bear fat tasting different, the only time we have found it to have a flavor (not good usually) is boars shot during the rut or fall bears eating skunk cabbage. I have been told salmon can make their fat strong tasting but I have no experience there. We shoot several bears a year that have been gorging on blueberries and it does not add flavor or taste.
