Difference between pasta, spaghetti, and pizza sauce

The spaghetti, pizza, and marinara sauce all are tomato-based sauces and they differ from each other based on the complexity of different added ingredients and spices in it.

Spaghetti sauce

Spaghetti sauce has a high amount of spices and extra ingredients like vegetables or beef added to it and that makes it fuller and tasty. It is essentially topped over and eaten with spaghetti.

Pizza sauce

Pizza sauce is the simplest of all three and it is the one that contains that minimum amount of added ingredients. Mostly it is tomato sauce with a few spices. Or we can simply say that a pasta sauce is essentially just a simple tomato sauce.

Pasta sauce

Pasta sauce has more spices, herbs, and condiments added to it than the pizza sauce but does not have any other vegetable apart from tomato and onion in it. It belongs to Italian-American cuisine and tastes delicious when topped over pasta.

How to tell if pasta sauce has gone bad?

A couple of indicators point out bad pasta sauce. You can tell if your pasta sauce has gone bad by considering its appearance, smell, and taste as well as the condition of the can or bottle in case of store-bought pasta sauce.

Appearance

If you see some mold or dark spot in the sauce, or if there is a discoloration in the sauce, then it is an indication that your pasta sauce has gone bad. 

Smell

Off-smell like intense sour or tangy smell is also an indication that it is time to get rid of the sauce.

Taste 

If the pasta sauce has passed both the visual and sniff test then you can go ahead and taste it. While tasting whether your pasta sauce has gone bad or not, only taste a bit of sauce as you don’t want to suffer from any gastrointestinal issues afterward. If you taste off-flavors then it means your pasta sauce has gone bad.

Condition of bottle

In the case of the unopened bottle of pasta sauce that has been there for a long time, if you notice a bulging lid or a bloated bottle, it is an indication that your pasta sauce has gone bad. The reason behind the bulging is the gases that are formed as a result of microbial contamination.
