Storage: Store the sauce in a non-reactive container in the refrigerator for up to 4 days. Check for sourness before using. It can also be frozen for up to 2 months.
Reheating: To reheat, place the sauce in a non-reactive pan over medium-low heat, stirring frequently to prevent scorching.
Chile Varieties: Fresh New Mexico green chiles are preferred for the best flavor. If unavailable, fresh poblano chiles are a good substitute. Frozen prepared chiles are acceptable. If using canned chiles, rinse them thoroughly. For dried chiles, soak in hot water for 45 minutes to rehydrate, then drain, seed, and chop.
Customization: Feel free to adjust the ratio of mild to hot chiles based on your preferred spice level.
