Crushed tomato can be brought already in a can or it can be made in the kitchen. Crushed tomatoes are a mixture of more finely diced tomatoes in a tomato puree. They have a much smoother texture and add thickness that's ideal for pasta sauce, lasagna, and Murgh Kari (a type of chicken curry). Making crushed tomatoes from scratch makes a fresher product which can be adjusted to your own thickness and or consistency and seasoned to your taste or left plain for use in recipes.
