I have no I idea where I saw this but some person or cooking show or something like that did a test between fresh pumpkin and canned. The fresh took some much time and effort, plus you have the get the right kind of pumpkin which is not usually sold in many stores. In the end I believe they said it was fine but the canned stuff just tasted better.
Also, I’m just now realizing I bought my pumpkin puree from Aldi (discount grocery store) and it’s the store brand. I bet this is the main thing I should look to improve on. Ingredient quality. I should have gone with a better name brand.
