Right - supermarket green (or red!) pesto. Can you/should you eat it straight from the jar without heating it up?
I tried using some for the first time today, heated it through and mixed it into pasta. It was rank. Yet when cold, it smelled delicious. It it better eaten cold from the jar?
Also how have I reached the age of 40 and never known what to do with pesto? Is there some public flogging I should attend for my ignorance?
