If you look really closely at the photograph above, you may notice some small black flecks. They are burnt bits of onion, celery, carrot and garlic. Unusually for me, I left the pot unattended while I watched some TV and before you know it, the 'aromatics' of my rich tomato sauce were charred. The more common problem I have is no patience, rarely being able to wait for things to brown properly or saute to a soft consistency, so it's strange for me to get to this level of neglect. (I'm not going to admit what I was so engrossed in on TV)!
