Vegetarian mock duck, also known as vegetarian roasted duck or vegetarian duck, is a plant-based alternative to the traditional roasted duck commonly found in Chinese cuisine. It is made using vegetarian ingredients to replicate the appearance and texture of duck meat while being suitable for vegetarian or vegan diets.

The specific ingredients used in vegetarian mock duck can vary depending on the brand or recipe, but common ingredients include wheat gluten (seitan), soy protein, mushrooms, tofu, and various seasonings and spices. These ingredients are often mixed together, shaped, and then cooked or roasted to create a meat-like texture.

Vegetarian mock duck can be used in various recipes that traditionally call for roasted duck, such as stir-fries, noodle dishes, soups, or even enjoyed on its own as a main course.

Here's a general recipe for vegetarian mock duck:

Ingredients:

• 1 cup wheat gluten (seitan)
• 1/4 cup soy sauce
• 2 tablespoons vegetable oil
• 1 tablespoon hoisin sauce
• 1 tablespoon soybean paste (optional)
• 1 tablespoon sugar or sweetener of choice
• 1 teaspoon five-spice powder
• 1 teaspoon sesame oil

Instructions:

1. In a mixing bowl, combine the wheat gluten (seitan), soy sauce, vegetable oil, hoisin sauce, soybean paste (if using), sugar, five-spice powder, and sesame oil. Mix well until the ingredients are evenly combined.
2. Knead the mixture for a few minutes until it becomes elastic and firm.
3. Shape the mixture into a log or a desired duck-like shape.
4. Preheat the oven to 180°C (350°F). Place the shaped mock duck on a baking sheet lined with parchment paper or foil.
5. Bake the mock duck in the preheated oven for about 30-40 minutes, or until it becomes browned and firm.
6. Once cooked, remove the mock duck from the oven and let it cool slightly before serving.
7. Slice the mock duck into thin pieces and use it in your desired recipes or enjoy it on its own.

Please note that this is a general recipe, and variations may exist depending on personal preferences and the brand or recipe being used. Adjustments to the seasonings and cooking times may be necessary to achieve the desired flavors and textures.
