ITV News Anglia has been looking at cooking up food for free that has been gathered from the region's fields, hedgerows and woodland.
As part of the filming, a horseradish was dug up and presenter Emma Baker took up the challenge of making it into a sauce. Here's the recipe:
Peel and finely grate the horseradish. Add a good dollop of yoghurt and cream - how much will depend on how strong you like your sauce.
Add a generous squeeze of lemon juice to taste and voila! Homemade horseradish sauce, best served with roast beef or smoked fish. Bon appetit!
