Over medium heat, warm the chicken stock. Once simmering, whisk in the grits and turn the heat down to low. Cook for 10 minutes and add the cream, still whisking. Cook for 15 more minutes, until tender.
While the grits cook, season the shrimp and cook over high heat, until pink. Set aside until grits are ready. Once ready to serve, whisk in the cheddar cheese and butter into the grits and serve shrimp over grits with a splash of hot sauce.
