S.B.
I've noticed the same thing with frozen peas. I've bought frozen green beans and corn from Costco and they don't have any additives, and I think they have frozen peas too, I haven't checked yet. I bought some canned peaches and pears that have no added sugar, it's just plain fruit and fruit juice, same as you get from commercially jarred baby food. I don't have a food processor, so I use my blender. I was a little discouraged at first, but after I played with the speeds, I found it wasn't too hard to puree. Also, the key is to add plenty of water/liquid! Some food you don't need to cook and puree, like bananas and also avocados, so easy, just mash and serve. I also buy big jars of regular applesauce (no added sugar) and my boy loves it!
