Can I Use Ketchup Instead Of Tomato Sauce

Tomato sauce and ketchup are oftentimes confused with one other due to some shared ingredients, like tomatoes, vinegar, and sugar, but beyond that, they are fundamentally different and should not be used interchangeably. Ketchup is primarily used as an accompaniment to a dish, while tomato sauce is the base for creating a variety of Italian-inspired meals. And while many people assume that all tomato sauce is the same, the truth is that a variety of recipes for tomato sauce exist, and can be crafted to suit a wide variety of dishes, flavors, and menus.

So, what makes tomato sauce and ketchup different? To begin with, tomato sauces tend to a have a thinner, more liquid consistency than ketchup. Ketchup usually contains additional ingredients, like additional spices and even fruits like peaches or apples, to add a unique and unmistakable flavor profile that is absent from regular tomato sauce. Its texture is thicker and almost paste-like. Ketchup also often contains far more sugar and starches than tomato sauce to give it its sweetness. Tomato sauce, on the other hand, often includes the addition of plentiful herbs and spices, like oregano, basil, garlic, and black pepper.

He also notes that it takes significantly less time to put together a tomato sauce than it does to make a ketchup from scratch.
