How to store the pesto: any pesto you don’t use can be stored in the fridge in an airtight container or jar. It should last a week or two. If you want to keep it longer, I would advise adding it to a jar and levelling it out so it’s nice and flat. Then add some olive oil over the top to create a layer that essentially seals the pesto. This will stop it going bad as fast. The olive oil will solidify a bit in the fridge but once mixed into the hot pasta when you use it, it’ll melt.

How to store basil: any leftover basil should be stored in the following way to keep it alive and strong for a good week. Slice the ends off the basil stalks and place in a small glass or mug in around 1cm of water. Take a clean sandwich bag and cover the basil with it, pulling the bag down the glass. Then seal the sandwich bag around the glass/mug. Leave at room temp.
