Where do you store / freeze baby purses? any product recommendations?

S ⭐️⭐️⭐️
I'm a FTM and my baby is almost 5 months old. I'm getting overwhelmed to the fact that my baby will start solids and I'm also working full time. Can you please recommend products where you store your baby's food. And those baby food purée maker like the one in the pic, are those helpful at all or is it a waste?
