Hazeli's Tomato Sauce

Hazeli's Tomato Sauce

1 28-oz can whole or chopped tomatoes, drained (Hazeli recommends imported San Marzanos or Muir Glen chopped)
4-5 tbls. butter (not margarine! very important!)
1 whole onion, peeled and halved
Salt to taste
Fresh basil if you wish

Combine tomatoes, butter, and onion in a pan over medium heat; bring to a simmer until the butter melts and combines. Lower heat so it simmers gently. Cook 45 min, discard the onion, and blend. If you like, a little fresh basil toward the end wouldn't hurt. Salt lightly at the beginning, then adjust at the end.
