Tomato Paste, Purée, Juice, Gravy, Soup, Sauce, Ketchup

Some questions I had when I started cooking that I think other beginners might also have:

What is the difference between tomato ketchup and tomato sauce?
What is the difference between tomato sauce and tomato paste?
What is the difference between tomato paste and tomato puree?
What is the difference between tomato puree and tomato juice?
What is the difference between tomato juice and tomato soup?
What is the difference between tomato soup and tomato puree?

What it is called in one country may be called as something else in another country.  But there is a sure difference in either cooking methods or consistency for each of them.


My thoughts:

tomato juice
churning raw tomatoes in processor until thin liquid.  raw tomatoes and tomato juice is healthy, and can be consumed as is, tastes better with black salt, sugar & chaat masala.  my aunt used to feed my baby sister so many tomatoes her cheeks used to look like tomatoes.


tomato ketchup
raw tomatoes/tomato juice cooked with veggies (like onion/garlic) and several seasonings on low heat then churned and strained to get smooth and thick dropping consistency.  also called tomato sauce by some.  ketchup is what you eat with your fries, burger, pizza, etc.


tomato purée
briefly cooking tomatoes in boiling water until soft, then churning in processor until smooth thick liquid and straining to remove seeds/skin/pulp (optional).  you could cook tomato juice till color changes and use as purée instead, depending on recipe if one can be replaced by another.  different methods of cooking (boiling then churning vs. juicing then cooking) sure bring minor taste differences.  learn how to make tomato puree at home.


tomato soup
cooking tomato purée along with vegetables, herbs, and spices (or cooking these with raw tomatoes and then churning in food processor) until it boils and becomes medium-thick liquid.  drizzling heavy cream over it, throwing in a few croutons, and garnishing with a mint leaf - this is the most basic and favorite soup in the world.


tomato sauce
cooking the tomato purée until a thicker, chunkier consistency.  different herbs, spices, vegetables may be added and left as chunks instead of churning, such as making the basic marinara sauce for pizza or pasta.  do you notice the difference between tomato ketchup and tomato sauce now?


tomato gravy
cooking either tomato juice or tomato purée along with veggies like onion/garlic/ginger/green chilies, some spices and herbs and making a thin/thick tomato gravy base to which variety of vegetables or paneer, etc can be then added and cooked further.


tomato paste
tomato juice cooked with optional minimal ingredients like garlic, chili powder, etc for flavoring, and salt & lemon juice for preserving, until thick concentrated paste.  this tomato paste can further be used for tomato gravy or sauce by adding water until appropriate consistency.
