One that often raises questions is the Jerusalem artichoke, a versatile and nutritious tuber. The key challenge many face is how to store them post-harvest to maintain their freshness and flavour. Here, I'll share tried-and-tested methods that are particularly suited to our UK climate.
Quick Answer
Store Jerusalem artichokes in a cool, dark, and well-ventilated place. They can be kept in damp sand or soil for up to 5 months.
Understanding Jerusalem Artichokes
Jerusalem artichokes, also known as sunchokes, are tubers that grow in the soil. They're hardy and can thrive in the Midlands climate. Harvest time is typically from late October through to early March. Once harvested, proper storage is crucial to prevent them from becoming soft and losing their taste.
Best Storage Practices
1. Keep Them Cool and Dark
The ideal storage temperature for Jerusalem artichokes is around 0-5°C. A cool cellar or a dark shed in Staffordshire would be perfect.
Ensure the environment is dark, as light can cause the tubers to sprout.
2. Use Damp Sand or Soil
One effective method is storing them in a box filled with damp sand or soil. This mimics the natural conditions of the earth and helps maintain moisture levels.
- Fill a wooden box with sand or soil.
- Ensure the sand/soil is damp, not wet.
- Place the artichokes in layers, with sand/soil in between.
3. Avoid the Fridge
While it might be tempting to use the fridge, it’s not ideal for long-term storage. The humidity levels can cause the tubers to go soft.
Timing and Seasonal Considerations
In the Midlands, we experience a range of temperatures, which means timing your harvest and storage is crucial. Here's a simple table to guide you:
| Month | Task | Conditions |
|---|---|---|
| October | Begin Harvest | Cool and moist |
| November - February | Main Storage | Cold and stable |
| March | Final Harvest and Use | Warming |
