Wash, scrub and drain the mushrooms. Pat them dry with a towel.
Place them in a colander atop a big bowl and sprinkle 1 TBSP sea salt. Toss to cover them all in the salt and leave them for about 30 minutes at room temp.
Rinse the mushrooms well to get rid of the extra salt and gently squeeze out as much of the water as you can without making a mash out of your mushrooms. Pat them dry with a towel.
In a bowl mix the ingredients for the marinade I do this while they are sitting in the salt. – Olive oil, vinegar, garlic, lemon zest, spices. Add the mushrooms and toss to cover them in the marinade.
Cover the bowl and put the mushrooms in the fridge for at least 30 minutes.
Enjoy chilled with your favorite raw crackers or wholegrain toasted bread. They make a great addition to salad too !
