Potted

The only picture I took today: five small pots of basil and sesame seed pesto ready to go into the freezer.
I was especially pleased to employ the little plastic containers that came with the left-overs of a takeaway meal (not mine) and which I had saved as potentially  useful.  
I imagine that squillions of these sauce pots are thrown away every day the world over and I am in no way endorsing their value. Surely they could be made of paper or some other degradeable material?
