Yes, tomatillos can continue to ripen on the counter if they are not quite fully ripe when picked and are left in their husks.
Understanding Tomatillo Ripening
Tomatillos, often mistaken for small green tomatoes, are distinct fruits typically harvested when their papery husks have just filled out and begun to split, revealing the firm fruit inside. While they are usually used green in recipes, they can develop a sweeter, less acidic flavor if allowed to ripen further.
For optimal counter-ripening, the tomatillos should be:
- Slightly Underripe: They should not be fully mature or overripe when harvested. A common sign is that the fruit has just started to swell within its husk.
- Kept in Their Husks: The papery husk plays a crucial role in the ripening process, helping to maintain humidity and protect the fruit. Removing the husk prematurely can halt ripening and lead to spoilage.
How to Tell if a Tomatillo is Ripe on the Counter
As tomatillos ripen on the counter, you'll observe several changes:
| Characteristic | Indication of Ripeness |
|---|---|
| Color | While often used green, some varieties may deepen to a richer green, or even develop yellow or purplish hues as they sweeten. |
| Husk | The papery husk will become dry, brittle, and typically split open further, pulling away from the fruit. |
| Feel | The fruit itself will transition from very firm to slightly softer, with a bit of give when gently squeezed. |
Tips for Ripening and Storing Tomatillos
To successfully ripen tomatillos on your counter and store them effectively:
- Leave Husks Intact: Always keep the husks on until you are ready to use the tomatillos. This protective layer is essential for both ripening and fresh storage.
- Room Temperature: Place them in a single layer in a cool, dry place away from direct sunlight. A kitchen counter or pantry shelf is ideal for short-term ripening.
- Air Circulation: Ensure good air circulation around the tomatillos to prevent moisture buildup and mold.
- Check Regularly: Inspect them every few days for signs of ripening or spoilage. Discard any that show signs of mold or rot.
- Refrigeration for Storage: Once fully ripe (or if you don't plan to use them immediately after picking), tomatillos can be stored in their husks in a paper bag in the refrigerator for several weeks. This will slow down further ripening.
- Freezing: For long-term storage, remove the husks, wash the tomatillos, and they can be frozen whole or chopped.
