Soak Dried Red Chili Pepper (25) in water for an hour and then grind to a smooth paste using a mortar and pestle or food processor.
Add Corn Oil (5 tablespoon) to a pan. Once it's hot, fry Garlic (8 clove), Ginger Paste (1 tablespoon), and Onion (1) for 2 minutes.
Add the ground chilli paste, Sichuan Peppercorns (6), Ketchup (2 tablespoon), Distilled White Vinegar (1 teaspoon), Soy Sauce (2 teaspoon), Salt (to taste), and Brown Sugar (1 teaspoon) in the oil and saute for 5-6 minutes.
Remove the pan from heat and let this sauce cool down completely. You can store this in a clean glass jar for upto 1 month in the refrigerator.
In a mixing bowl, add Chickpea Flour (2 cup). Add Salt (to taste), Garlic Powder (2 teaspoon), Onion Powder (2 teaspoon), Paprika (1 teaspoon), Ground Turmeric (1 teaspoon), Italian Herb Seasoning (1 tablespoon), Ground Cumin (1 teaspoon), and Garam Masala (1 teaspoon).
Add Water (2 cup) and whisk it all together ensuring that no lumps are formed.
Pour the chickpea flour mixture into the pan. Cook over medium heat and keep stirring continuously. The mixture will start to get lumpy as the pan heats up and then thicken evenly. This should take 4 to 5 minutes, but the time can vary. When the mixture stops sticking to the pan and has a thick batter-like consistency, it's done.
Take it onto a baking tray lined with parchment paper. Flatten it and let it set in the freezer for an hour.
Cut in any shape you want and use. For this recipe, cut it into rectangular pieces.
