Remove the stems from the chili peppers. If you prefer a milder sauce, you can remove the seeds as well.
In a food processor or blender, combine the chili peppers, garlic, ginger, ground coriander, and ground cumin.
Add the vinegar and blend until smooth.
Heat the vegetable oil in a small saucepan over medium heat.
Add the blended chili mixture to the saucepan and cook, stirring frequently, for about 5-7 minutes until the sauce thickens and the raw smell of the chili peppers fades.
Stir in the salt and lime juice if using. Adjust the seasoning to taste.
Allow the Sakay to cool to room temperature.
Transfer to a clean jar or container and store in the refrigerator. It can be kept for several weeks.
Enjoy your meal!
