Manufactured pasta sauces with a tomato base will, typically, include sugar.
I make my own, no sugar.

@guardeddon Not sure what you mean, tomato sauce would have sugar in it if you make your own or not. Tomatoes have sugar in them so you can not make a sauce at home without sugar. In fact only way to make a sugar free sauce would be with a manufacturing process that removed the sugar from tomatoes.

@freemo Added sugar. In addition to naturally occurring in the fruit.

@guardeddon Ahh ok... that still seems like a very odd distinction to make though. Not trying to give you a hard time, just trying to understand why yoru phrasing it that way or what information your trying to convey.

Why is it different if the sugar gets in there as part of some other ingredient or in its own? If at home I add cane syrup to my food it doesnt count as added sugar cause its just juice from a plant? But if i dry it out first it counts as sugar?

Are you just trying to say store bought sauce tends to have more overall sugar content then when you make it at home because they use a recipe that is higher in sugar content? If so that makes sense then but wouldnt apply here, its a restaurant and home made most likely.

@guardeddon Also by the way traditional northern red sauce recipes actually include sugar, southern recipes tend not to.

@freemo I should have been clear, I mean added sugar, not the naturally occurring sugars. Tomato is a fruit so, yes, natural sugar. Manufacturers of processed foods tend to add sugar.

@guardeddon Yes i know what you meant, but its confusing because all sugar is natural and from plants. Raw sugar is just sugar cane extract. Raw sugar is no different than sugar when its still inside the plant.
