I sweated celery with garlic, and added the rice, then soaked some porcini in hot water to add later. Once I'd started adding stock I threw in the plumped up porcini, its water, some frozen peas, lamb, and at the end a smattering of mint and parmesan.
The result was a minted pea and lamb risotto. Possibly one of the oddest things Ive ever made, but it was actually really nice. A lot nicer than it possibly sounds anyway :)
