Pickling food is a traditional way to preserve food but it also imparts an amazing flavour to a whole array of vegetables. I love mushrooms and always looking for new ways to serve them so pickling them seemed an ideal way to jazz them up. You can use any mushrooms but they are better left whole so opt for button mushrooms or small shiitake mushrooms. These are delicious on their own or served as part of a main meal. Great smothered over toast for breakfast too. Instead of using a brine I have marinated them in vinegar with plenty of herbs and spices. Ideally make these a few days before you want to eat them.
