The title pretty much says it: What is the difference between marinara and spaghetti sauce?
I Googled and got a bunch of hits but none of the answers left me feeling like I actually understand the difference. If anything, I'm more confused now than when I started. The one thing that a few of the answers I found had in common was the idea that marinara sauce is simpler, with fewer ingredients than other tomato-based sauces. Still, the idea does not present the full picture. I guess another way to approach this question would be to ask: What would one add to "marinara" sauce to make it "spaghetti" sauce?
