You will want to look for key factors when making your decision which
bag to select, including the actual capacity of the
bag, affordability, compatibility with breast pumps (and / or nipples), how well it will hold up
in the fridge or
freezer and any
special features it offers to make your life easier.
I keep a
bag of homemade almond flour from soaked almonds
in the
freezer most of the time to make grain free pizza crusts, so
special prep of the almonds before making these cookies was not necessary.
