@Louise nadine brillwas going through this post about your Peach PDF, have you tried adding a supporting fruit like apricot? I know Boiron has an amazing PDF chart that i use as a rough guideline. I know you can use their peach puree on its own, but I find with delicate flavors that can lose their flavor integrity when cooking it can be beneficial to use a supporting booster fruit. Some fruits like Pineapple, Lime, etc have to be supported due to the acid amount or enzymatic activity, like bromelain, but in doing so you use the base fruit (usually apricot or peach), cook, then add the other purees closer to the end of cooking. They turn out less jammy/oxidized/caramelized and the flavor pops more.
