Peel and finely slice the garlic, finely slice the chilli, then roughly tear the mushrooms. Add the olive oil, butter and garlic to a large non-stick frying pan over a medium-high heat. Fry for 1 minute, add the mushrooms and chilli, then pick in the thyme leaves. Season with salt and pepper, add 100ml of boiling water, then cook for 8 to 10 minutes, or until softened.
Meanwhile, make the fritters. Place the ricotta into a large bowl and beat until smooth. Add the flour, egg and a few gratings of lemon zest. Finely grate in the Parmesan and ¼ of a nutmeg, season with salt and pepper and mix well to combine.
Heat a good splash of olive oil in a medium pan over a medium heat, then add heaped tablespoons of the mixture (you’ll need to do this in batches), making sure you space them out nicely. Cook for 5 to 6 minutes, or until golden and cooked through, turning halfway, then transfer to a plate.
Pick, roughly chop and add the parsley leaves to the mushrooms, add a squeeze of lemon juice and toss well. Divide between your plates, top with the fritters and enjoy.
