Step 1

An uncooked cut sweet potato should be kept submerged in cold water in the fridge.

Step 2

In an airtight container the potatoes will last for 3-4 days, but for the best quality eat them within 24 hours.

Step 3

The water must be cold. The fridge will do a good enough job of keeping the water cold, but some people like to put a few ice cubes in with the water to keep it as cold as possible.

Step 4

It’s best to avoid freezing uncooked sweet potatoes unless you blanch them first.

Step 5

Peel and cut the sweet potatoes

Step 6

Put the cut sweet potato into boiling water for 2-3 minutes depending on the size of the pieces

Step 7

Transfer the sweet potatoes straight into ice-cold water and leave them there for a further 2-3 minutes. This stops the cooking process

Step 8

Once you’ve blanched the potatoes you can portion them out and put them in freezer-safe bags. Portioning the potatoes out is very important because they'll stick together once they’re frozen.

Step 9

You can also date the bag so you’ll know how long they’ve been in the freezer.

Step 10

The sweet potatoes will last around 6 months in the freezer.
