They've only recently become a familiar sight in supermarket freezer aisles, but frozen leeks are a handy vegetable to have in stock, and don't go as soggy as you may think. Frozen within hours of harvest to capture the flavour (which they retain) and freshness, you can cook them straight from the freezer to use as a side to a main meal, throw into soups or in pasta.

Top tip: Run out of onions? Leeks are a great substitute in soups, stews and omelettes.
