Porcini are one of the most prized mushrooms. They are dried for preservation and when rehydrated in water they bestow their powerful, almost meaty flavour to the liquid. This tart uses that liquid and other mushrooms, as well as the porcini themselves, so it is crammed with mushroom flavour.
One of my favourite ways to serve steak is this traditional French bistro method. Pepper, a seasoning that often hides in the background barely noticed, is thrust onto centre stage. Where normally we grind peppercorns into a fine powder, here they are left in larger chunks so you notice the flavour and texture as well as the heat.
If you are cooking this dish for quite a few people, you can lay the fish on an oiled oven tray, drizzle a little oil over the top of each fish, and cook under a hot grill for 3–5 minutes on each side or until the skin is crispy and the fish opaque all the way through.
This dessert from Rachel Allen is perfect for entertaining as it can be made in up to two weeks in advance.
