You put Basil in the Ratatouille?

I bought this cheap ready-to-grow Basil pot in a pound shop after my first ever trip abroad to Rome in April this year. I had a fair few of the best pasta dishes I'd ever had and this was a memorable flavour. It has been growing quite nicely on our bedroom windowsill all this summer. We have only harvested a couple of leaves so far as we're scared we might take too much and end up killing our Basil baby.
