Zero-waste home dried mushrooms

A couple of years ago, I spent too much money on veg in a farm shop. This is not unusual. A barbecue for all fifteen members of the Storr clan was needed; about half of the adults insist on vegetables (the other half seem to find them garnish). I love to barbecue mushrooms, sweetcorn, cauliflower, tomatoes. So, I bought them.

Mushroom burgers on the barbecue, stuffed full of garlic and parsley butter was what I wanted. I stacked the pan full of charcoal, flipped open a cider and watched the little cousins play in the courtyard. It was the headless space I needed, adding coals to the fire and hitting them with a heavy, dusty poker.

Somehow the mushrooms never made it as far as the barbecue. Back home, through a mind blasting hangover, a heatwave and business, 4 fat mushrooms were starting to decay in my fridge. And I didn’t want the fucking mushrooms or anything that looked backwards.

So I sliced the mushrooms, laid them onto greaseproof paper and shoved them in the oven. A couple of hours later I had a home-grown version of porcini; not as fancy or full of flavour but a million times cheaper (don’t quote me on that stat). Your leftover mushrooms can be used tomorrow, in 2 months or a year.
