In a large pot over medium heat, add the chopped bacon and cook until browned and the fat has rendered. Set the bacon aside, reserving about 2 tablespoons of the fat in the pot. You'll be using the cooked bacon to garnish later.
Turn the heat to medium low. Add the onions, garlic and mushrooms. Cook until the onions and mushrooms are soft, stirring every minute or so. This will take about 8 to 10 minutes. Place the mixture in a container (you'll be adding them back later).
Add the butter to the pot and melt. Add the flour and stir until no lumps remain. Cook until the flour has lightly browned. Add the half-and-half while stirring, and whisk to ensure there are no lumps. Add the turkey stock and oyster liquor while whisking.
Add the potatoes and the cooked mushroom/onion mixture. Adjust your stove's heat until you reach a slow simmer. Cook until the potatoes are just fork tender (aldente).
Add the cooked wild rice, shredded turkey meat and the ground sesame seeds. Cook at a slow simmer for about 8 minutes while gently stirring often.
Season to taste with salt, black pepper and cayenne pepper. Add the sherry of using.
