In regards to the pumpkin pie, it could be the brand of puree you are using. Are you using solid pumpkin puree (not pumpkin pie filling)? Smell it and taste it to make sure you like it before using. Here is a drill-down on
Pumpkin Puree.
You shouldn't need to add more sugar to this mix. The sweetened condensed milk gives the filling a nice balanced flavor. If you have time, try it again and perhaps buy a different puree to compare. It really is a nice pie. Pumpkin pie isn't one of my favorites but I don't pass up a slice on this one.
Happy Thanksgiving!
