Another worthy replacement for smoked paprika is ancho chili powder. It’s made from dried and ground ancho chiles. This pepper is more common in Mexican cooking but found its way into the United States by way of Tex Mex cuisine. They offer mild to medium heat that only ranges from 1,000 to 1,500 SHU. It has a deep, smoky and slightly sweet flavor. For this reason, you don’t have to worry as much when using this as a replacement as it won’t overpower your dish as easily compared to chipotle powder. To use as an effective backup, you can incorporate exactly how much a recipe calls for smoked paprika.
What Can I Substitute for Paprika?

So, if bell peppers are in the same scientific classification as cayenne chili pepper, why aren't bell peppers hot? It comes down to a chemical compound called capsaicin. This chemical is the sole reason why a jalapeño is spicy and bell pepper is not. A bell pepper has no capsaicin. Capsaicin attaches itself to the mucous membranes in our mouths which in turn send out the fiery sensation. That heat in your mouth (or hands) will vary greatly depending on what type of chili pepper you've eaten. Peppers are ranked by their heat, or the amount of capsaicin they contain, on a scale called the Scoville Scale. Their capsaicin concentration is given a number on the scale and it is called Scoville Heat Units. Bell peppers do not have capsaicin, so they have zero Scoville Heat Units, therefore they are way at the bottom of the Scoville scale.
To incorporate in dishes with paprika, use one teaspoon of gochujaru powder for every teaspoon of sweet or mild paprika. Of course, you may add more if you want more heat.
When you slice a bell pepper in half it will look exactly like any spicy chile pepper. There is a placenta covered with seeds, there are veins running along the flesh of the bell pepper. They are pretty much identical with the main exception being the difference in size. Bell peppers have a fruity scent, just like many hot chilies. Both have a crispness to their flesh and also high water content. You can slice, sauté, grill, char, pickle, stuff, or eat bell peppers just like you would any kind of spicy chilies. But when it comes to bell peppers you'll never have to wear gloves to protect your skin from a chili burn, and you'll never have to reach for a drink to calm the fiery heat after eating bell peppers.
