Handling Habaneros: Wear gloves or be extremely careful not to touch your eyes or face after handling them. Wash your hands thoroughly afterwards!
Getting the Right Thickness: Make sure your sauce is simmering when you add the cornstarch slurry. If it feels too thin after 4 minutes, make another small slurry (like ½ tsp cornstarch with 1 tsp water) and stir it in, simmering for another minute or two. If it gets too thick as it cools, you can thin it with a tiny bit of hot water or lime juice when reheating.
Cool Before Storing: Always let the sauce cool completely before transferring it to an airtight container.
Storage: Once completely cool, transfer the sauce to a clean, airtight container or jar. Store it in the refrigerator. It should keep well for 1 to 2 weeks. Just give it a quick stir before using, as some separation is natural.
