Freshly harvested celeriac roots in a garden

As a gardener with over 15 years of experience in Staffordshire, I’ve learned a thing or two about keeping vegetables fresh post-harvest. Celeriac, with its unique flavour and versatility, is a favourite in many UK gardens, particularly here in the Midlands. However, storing it properly is key to ensuring it stays fresh and delicious for as long as possible.

Quick Answer

To store celeriac, keep it in a cool, dark place with high humidity. Wrap in paper or place in damp sand, and it can last for 3-4 months.

Importance of Proper Storage

Celeriac, often called celery root, is a hardy root vegetable that thrives in the UK climate. Proper storage is crucial to maintain its texture and flavour. Without it, your celeriac can quickly become tough and flavourless.

Preparing Celeriac for Storage

Once harvested, shake off excess soil but don’t wash it. Moisture can lead to rot, so it’s better to keep it dry. Trim any greens, leaving about an inch of stem.

  • Leave a small portion of the stem attached
  • Do not wash before storing
  • Remove excess soil gently

Best Storage Techniques

Cool and Dark Environment

The ideal storage conditions for celeriac are similar to those of other root vegetables. Aim for a temperature of around 0-5°C.

High Humidity

Celeriac prefers a humid environment. A simple way to achieve this is by wrapping the roots in damp newspaper or placing them in a box with damp sand.

Storage Duration

When stored correctly, celeriac can last for several months. Here’s a quick guide:

Storage Method Environment Duration
Damp Sand Cool & Humid 4-5 months
Wrapped in Paper Cool & Humid 3-4 months

Things to Avoid

Avoid storing celeriac in a plastic bag, as this can trap moisture and encourage mould. Similarly, don’t keep it in direct sunlight or a warm spot.

Frequently Asked Questions

Can I freeze celeriac?

Yes, you can freeze it. Blanch it in boiling water for a few minutes, then cool and freeze. However, it may lose some texture.

What are signs that celeriac has gone bad?

If you notice soft spots, a strong off smell, or any mould, it's best to discard the celeriac.

Is it necessary to peel celeriac before storing?

No, it’s best to leave the skin on. Peeling it can expose the flesh to air and increase the risk of spoilage.
