I just use a bag clip for crisps and for meals I got reusable pouches from Amazon.
@Klaudia how long would you say your purée lasts in the glass jars?
I use a food bag clip x
@Toni my son loves his food so I never needed to keep it for more than 2 days
I've batch cooked purees and other recipes from Ellas Kitchen book and then put into the larger ice cubes trays. Once frozen I pop them out and keep them in freezer bags in the freezer with a label on and date. Usually should be fine for a month. Maybe veggies alone a bit longer. So easy just popping a few out of the bag to defrost in the morning x
close them in the original packaging with a clip I store purées in the fridge in glass jars 🫙
