Hi, I am planning on make a pumpkin beef soup/stew, wherein I roast some pumpkins and them puree them, using it as the base for the soup. I am planning to simmer some sort of beef in the pumpkin puree for a couple of hours probably. I was wondering if the extra cooking of this puree for a couple hours will degrade the taste or quality? Would it be better just to cook the beef in a different way and then add it to the pumpkin puree when it's done? I feel like that would lose some of the beef flavor though that would otherwise be imparted to the pumpkin puree. I also plan on adding some beef stock to it. Thanks for any info.
