Roughly chop the onions, garlic, mangoes, and habaneros. You can remove the chile seeds if you want to tame the spice in this sauce. Don’t forget to handle the habaneros with care, and wash your hands thoroughly afterward.
Heat some oil in a pan, then sauté the onions until translucent, followed by garlic. Add the habaneros and mangoes last, then pour in the water and finish cooking until the mangoes are softened.
Transfer the sautéed ingredients to a blender, add lime juice and salt, then blend the salsa until the consistency is smooth and creamy. Taste and adjust the seasonings, or add more liquid if you prefer it thinner. Happy eating!
