Wild Garlic
It will be soon that time of year again when wild garlic starts growing in hedgerows and woodland.
Free food that is good for you.
Firstly be sure what you are picking is wild garlic and not other plants such as Lily of the Valley which will make you ill. Lily of the Valley does not smell of garlic. Clear identification of wild garlic can be found here https://totallywilduk.co.uk/2018/11/10/wild-garlic-identification-allium-ursinum/
This incredibly diverse herb can be used not only in exactly the same way as garlic is used traditionally for flavouring and seasoning, but you can add the leaves and flowers to salads, stir fries, roasts, again, what you do is really limited by your own invention.
