Simmering Overnight

I simmered my tomatoes overnight in the slow cooker at 225. Next I will put them through the food mill. It is comforting to have things cook themselves, safely. When the liquids have cooled, I puree the remaining pulp in a little bit of tomato liquid in my blender to add back into the sauce. Important warning: don't puree in blender until everything has cooled off otherwise you will have exploding hot liquids on the ceiling.
