I bought a bag of basil leaves recently, only to discover another bag sitting at the bottom of the fridge when I got home. I'd completely forgotten about it. It was practically full but only slightly wilted, but I hated the idea of letting it go to waste.
I then realised that I also had some leftover walnuts in the cupboard from when I made gluten-free chocolate brownies, so I decided to try making some pesto with the basil and walnuts.
I threw the basil leaves, walnuts, parmesan cheese and some olive oil into the blender and blitzed away. I found that the pesto needed more cheese than normal, probably due to the strong nature of the walnuts, but it turned out delicious.
I poured it into a container and poured a thin layer of oil on top to keep it covered until it's needed.
