Mushroom, red onion and tarragon quiche

For variation in flavour and texture, I use different types of mushrooms, but you can use your favourite mushrooms or whatever is in season.

I’ve used crème fraîche in this recipe to add a little acid; you could use sour cream or a plain milk kefir instead. Fresh goat’s cheese provides a balance for the sweetness of the roasted onions – a more mature cheese will give a deeper flavour.
