Is it better to use canned pumpkin or fresh pumpkin? Canned pumpkin pie mix or just plain canned pumpkin?

Fresh but celebrate! I believe in fresh fruits&veggies/shopping in the periphery of the store. However, if you have a family recipe or something that you use once per year and it's canned pie mix, go for it! Generally speaking - fresh/single ingredients are better than mixtures/processed foods since you know more about what you're mixing with the single ingredients. We can definitely discuss more about sugars, etc.
Yes . fresh pumpkin is the best. Canned plain pumpkin is the .try to avoid processed foods natural foods are healthier.
