Stir in the rice, porcini, and garlic. Continue to stir until the rice grains separate and start to crackle.
Pour in the wine and stir until it's no longer visible in the pan.
Add the simmering stock in small portions (about ½ cup) at a time. Ensure the stock covers the rice and maintains a gentle simmer, neither slow nor fast.
Cook while stirring often until the liquid is nearly absorbed. Add another ladleful or two of stock as needed, continuing to cook and stir until the rice is almost dry. Stir frequently, but do not overdo
After 15 minutes, incorporate the turkey and peas and add stock as previously instructed. The risotto should be ready in 20 to 25 minutes when the rice is tender yet still has a chewy texture. Adjust the seasoning to taste.
