Having a clean and organized pantry or food bin does not only help in keeping the kitchen clean, but also helps in tracking food items. This way, it will also help you save money by not buying everything twice.
Unpack items systematically. You may want to unpack them on the table or counter first and group them according to where they should be placed.
Open packages which you will need to transfer to see-through plastic containers or other dispenser, if you have them. These are usually for sugar, coffee, salt, etc.
Stock items on your shelves or the fridge. If you have more than one item, place newer items at the back and place the ones that will expire first in front. Rotate everytime you use something and also when you buy somehting new.
