If you cannot find Sir Kensington's Chile Lime Crema, you can easily make your own by combining 1/2 cup of store-bought mayonnaise with the juice from 1/2 a lime, 1/8 teaspoon of garlic powder, 1/8 teaspoon of chile de arbol powder, 1/8 teaspoon of cumin, 1/8 teaspoon of mustard powder, and 1/8 teaspoon of cayenne pepper.
