This is a spicy, slightly smoky butter made with macha salsa. Macha is Mexican-style salsa with a bunch of dried chiles, fresh garlic, sesame seeds, and often nuts which make it a spicy, crunchy topping that you can use for tacos, veggies, salad dressing—it’s an everything sauce. This recipe has the addition of butter to make it perfect for topping steaks or spreading on fresh bread.
