Baby food, rice porridge, cooked rice Frozen, divided, pack Stocker, stock Set of 4 Solid, cube making Storage pack Convenient for dividing baby food. For making frozen stock. I used these for freezing and storing rice porridge during my child's baby food period. I used all the cubes, but since I used 4 in rotation, some weren't used much. All are used, so please forgive any minor scratches. I only used rice, so there is no discoloration!
