When it comes to replacing byadgi chili, there are several options available in the market that can add a similar flavor and heat. One of the best substitutes for this particular chili is Kashmiri red chili powder, which has a mild and fruity taste with less heat than byadgi. For those who prefer spicier flavors, they can opt for cayenne pepper or paprika powder as an alternative. Both these spices have a more intense heat level compared to byadgi but still, provide rich color to dishes. In case none of these options are available, one can use regular red chili powder mixed with smoked paprika to achieve a smoky taste similar to byadgi's unique profile. Regardless of which substitute you choose, remember that every spice has its own distinct quality and should be used accordingly based on personal preference and recipe requirements.
