Curing Your Sweet Potatoes
After harvesting your sweet potatoes, the first step is curing them. This process helps to heal any scratches or bruises and converts starches into sugars, enhancing their flavour.
Steps for Curing
- Keep them at 29-32°C (85-90°F) with high humidity (85-90%) for 7-10 days.
- Avoid washing them before curing; simply brush off excess dirt.
- Ensure good air circulation to prevent mould.
Ideal Storage Conditions
Once cured, sweet potatoes should be stored in optimal conditions to ensure longevity. The Midlands' climate can be quite variable, so finding the right spot is crucial.
Key Storage Tips
- Store in a cool, dark place at around 13-15°C.
- Avoid refrigeration as it can harden the core and affect taste.
- Keep them away from direct sunlight and heat sources.
