Prep the ingredients: Start by roasting or charring your green chili pepper (you can do this on a stovetop or in an oven). If you prefer a milder sauce, remove the seeds and stems from the pepper before using it.
Blend the sauce: In a blender, combine the roasted chili pepper, minced garlic, soaked cashews, pink salt, water, and lime juice (don’t forget to add the zest for an extra burst of flavor!). Blend everything on high speed until the mixture is smooth and creamy.
Taste and adjust: Taste your sauce and feel free to adjust the seasoning. If it needs more heat, add a little more chili. If it’s too thick, you can thin it out with a bit more water, or even a splash of olive oil for extra richness.
