My hubby is Italian and I make home made marinara. I don't cook it for 3 days though.
I don't have a "set" recipe... I just add things to our taste.
I use my automatic chopper and chop some onion, garlic and carrots.
Saute the veggies in a little butter until they are translucent.
Add 2 large cans of crushed tomatoes
Add a bit of sugar
Add Italian seasonings to taste
Personally, I chop about 4 anchovies and add to my mixture.
Simmer for an hour or so on very low.
I keep a jar of this in my fridge at all times.
My family loves it. When my daughter asks me someday for the recipe, she will just die to find out she's been eating anchovies all her life, LOL. She says she hates them.
This marinara does get better the longer it sits because the flavors meld together well.
