WHAT IS PAPRIKA?
Chili Pepper

Tomato sauce sports a nice bright red color and a sweet taste that mimics that of the sweet paprika. However, these qualities alone without the spice are not enough as a swap. Mixing it with chili powder will add the heat that tomato sauce lacks. There’s a catch, however. Since this backup is wet, it’s only good for recipes like stews and soups.
Paprika, a Hungarian term for pepper, is a ground spice made from dried red peppers. Depending on the preparation method, it varies in flavor from sweet to spicy and even smoked. Hungarian and Spanish paprika differ significantly: Hungarian varieties are often sun-dried, while Spanish versions are typically smoked over oak logs.

There are many different types of chili sauce, which is often more of a generic term of a sauce made with chili peppers.
