In a small saucepan, bring the chicken stock to a simmer over medium heat, then reduce heat to lowest setting just to keep warm.
Next, heat a medium sized skillet or dutch oven over medium. Add the butter, as soon as it melts add the minced shallot and cook, stirring occasionally, until softened but not browned, about 5 to 7 minutes. Add the rice and stir until evenly coated in butter.
Next pour in the wine and increase heat to medium-high. Cook, stirring frequently, until all of the liquid is absorbed into the rice, about 2 minutes.
Next, begin to gradually add the chicken stock, ½-1 cup (enough to just barely cover the rice) at a time, stirring frequently until absorbed before adding in more. Continue this process over a period of about 15 minutes, adding more stock as each previous amount is absorbed. Cook until rice is al dente and risotto is creamy and saucy, about 18 minutes total. (If you need more liquid because you run out of hot broth, you can simply use hot water.)
Turn off heat. Stir in the heavy cream, grated parmesan cheese lemon juice and zest. Season to taste with salt. Divide among 4 shallow bowls and garnish with preserved lemon and extra grated parmesan (optional). Serve immediately.
