When substituting, use common sense. Cayenne pepper is as much as 50 times hotter than sweet paprika, so a 1:1 substitution wouldn't work unless you want some heat—the right substitution, in this case, would be 1/3 of a teaspoon of cayenne per 1 teaspoon of paprika. Make an informed decision, but also use thorough recipes that might suggest reasonable substitutions.

We know it may be very tempting to simply swap in that ketchup sitting in the fridge, but spiciness is a primary expectation of chili sauce, and there’s obviously none in ketchup. Plus, it’s very simple to spice up that ketchup with chipotle or cayenne pepper to at least provide some heat.

When it comes to drying paprika peppers, there are a few methods you can choose from based on your preference and equipment available. Each method has its advantages, but using a dehydrator is generally considered the best approach, providing efficient and consistent results.
