Storage & Preservation
Fresh Poblano 'Tiburon' peppers store best in the refrigerator crisper drawer, where they'll maintain quality for 1-2 weeks. Avoid washing before storage and keep them in a perforated plastic bag to maintain humidity while allowing air circulation. At room temperature, they'll stay fresh for only 3-5 days.
For longer preservation, roast and freeze whole peppers in freezer bags for up to 8 months—perfect for year-round chiles rellenos. The thick walls of Tiburon make them exceptional for this method. You can also slice and freeze raw peppers, though they'll be softer when thawed.
To create homemade ancho chiles, allow peppers to fully ripen to red on the plant, then dry them using a dehydrator at 125°F for 12-18 hours, or air-dry in a warm, well-ventilated area for 2-3 weeks. Properly dried ancho chiles will keep for up to two years stored in airtight containers.
