We used to use a full gallon every week because DH was a big cereal eater. He changed to grits (made with water and butter) and I have trouble using the smaller bottle before it goes sour. I even tried buying the baby-sized bottles but they only do three bowls of cereal and they're gone so I'd need two, and that costs almost as much as a full gallon! So I've gone back to the regular-sized one, which leaves a lot of sour or nearly sour milk at the end of the week... what else can I do with it aside from making pancakes or throwing it out? I could make enough to feed an army!
