Place the content of each of your different infusions (green tea, peppermint, etc.) inside a glass jar. This will help your infusions stay fresh longer and also take less space in your cupboard.
Tip: to remember which is which, simply cut out the name from the infusion box and sellotape it on the side of the jar.
Tea bags are cheaper to buy in large packs but they would take too much space in the food cupboard for day-to-day use. So, I fill a handy-size container with a few handful of tea bags and, to keep the remaining tea bags fresh, I place the pack inside an old sliced bread plastic bag sealed at the top. To give you an idea of sizes, you can fit a 750g pack of Yorshire Tea tea bags inside a Hovis bag.
