In a saucepan over medium heat, melt the butter and olive oil. Add the garlic and tomato paste, cooking for about 4 minutes until fragrant.
The tomato paste will darken in color, reducing its acidity.
Stir in the red pepper flakes, black pepper, paprika, cumin, and salt. Combine well.
Add cilantro and lemon juice, mixing until a sauce forms. Adjust the seasoning according to your taste. For more heat, add extra red pepper flakes or sriracha. Set aside.
