Usually, no: mirch means chili, while a curry blend is a full masala. If a recipe asks for lal mirch, Kashmiri mirch, or deggi mirch, it is asking you to control heat and color. A curry blend changes the whole flavor because it brings coriander, cumin, aromatics, salt, and other spices along with the chili.
For plain chili color and gentle heat, choose Kashmiri Chili Peppers Whole. For a fiery, rounded curry seasoning based on Mathani chiles and supporting spices, choose Rajasthani Curry Jar - Limited.
