Grabbed these 5 cans of powdered milk at Walmart on my last trip there. These are 3.52lbs/1.6kg cans. These went straight to my stockpile for future use. These were marked off 50%, so each can came to $7.74! With milk prices going through the roof and a gallon of milk hovering around $3.50 or so, regular milk has been relegated to drinking and morning cereal only. I used to use evaporated milk for cooking, but I am down to my last can out of the stash I had on hand. Last time evaporated milk went on sale for $0.50 a can, I think I purchased around 40 cans? Since then, I have not seen them go on sale. Regular price for them now is around $1.30 or so a can, so you can see what a good deal these canisters of powdered milk were!
I have been using powdered milk in baking and cooking for about a year now. It is convenient to have on hand. No last minute trips to the grocery store because I don't have milk to use in a recipe. Taste wise, I think powdered milk is no different than regular milk in cooking. I have to admit I have not tried to actually drink the stuff mixed with water. What I have read is that if you do want to drink it, one must mix it in a container and chill it in the refrigerator first. Otherwise, it is my understanding that it tastes like yuck! I hope I never get to the point of having to resort to that! I have used powdered milk in Southern biscuits, milk gravy, pot pies and cake recipes with success. So if you come across deals like this, I recommend that you grab it! Unlike regular milk, these don't go sour on you!
