Answer:
Flour, baking soda, sugar/brown sugar, milk, eggs
Explanation:
Flour: Flour, in optimal conditions has a shelf life of about one year. Storage in a room temperature pantry is okay, but an ideal place for keeping flour fresh is in the freezer or fridge in an airtight container. Flour at room temperature generally goes bad after around 4-8 months, but in the freezer/refrigerator it can last 1-2 years.
Baking Soda: Can be kept in the box as is, but if freshness is preferred, transfer to an airtight container. No refrigeration is required, but make sure to keep a tight lid on it, as baking soda is prone to absorbing odors. Keep in pantry. Unopened, it can last 18 months, after opening it can last up to 6 months for the best quality.
Sugar: Do not put in the refrigerator. Moisture makes sugar hard and lumpy. Keep in a tight container in an odor free area. Keep in pantry. Technically, sugar never spoils, but it is recommended to keep it for at most up to 2 years.
Brown Sugar: Should be stored in an area that is cool and moist. Preferably in an airtight container. A resealable bag will work as well, as long as no air can get in to dry out and harden the sugar. Has a usual shelf life of about 6 months from opening.
Milk: Store on the refrigerator shelves as opposed to the refrigerator door. It is cooler the deeper inside the fridge you go, and for longevity's sake, it is best to keep the milk as far back as possible. Ideal temp for milk is between 0-5 degrees celsius. Milk should never be drank past the due date listed on the container.
Eggs: Should be stored inside their original carton on an inside shelf, not on the refrigerator door. Should be kept at roughly 4 degrees celsius or lower. Storing your eggs in the fridge is a good way to keep bacteria from infesting them, alongside keeping them fresher. They last about 3-5 weeks.
