Tomato Sauce with Onion and Butter

This sauce will impress, just stumbled upon this recipe here, but have made it hundreds of times. Essentials of Italian cooking by Marcella Hazan is a cooking Bible. This recipe is simple, you can easily make this on a busy week night, and is amazing. Once you try it you will say, “ where has this been all my life?” I personally don’t mix the onion in my pasta, but my husband slices up the onion and tosses it up with his. Personal choice. This sauce is so good, get an extra loaf of bread. When the pasta is done you will want to slop up every bit of sauce you have left. I have passed along this recipe to friends and they all say butter in tomato sauce that’s weird, but they all come back to tell me how amazing it was.

2 cups of canned tomatoes is not equivalent to 2 lbs fresh. This must be a misprint, yes?

How do you remove the onion?
