Grease the pan lightly with oil (any oil), making sure to grease the sides as well. Set the pan aside.
In a bowl, whisk together the chickpea flour, salt, sugar, granulated garlic, and turmeric. Pour in 1 cup (230g) of water into the bowl and whisk everything until you get a smooth batter. Set aside.
Pour the remaining water into a large stainless steel saucepan. I poured 1 3/4 cups (403g) water into the saucepan for a firmer tofu. Bring the water to boil and reduce the heat to medium. Give the chickpea batter a quick whisk. Then, pour the batter into the boiling water, making sure to whisk the contents in the saucepan as you pour the batter.
Continue cooking the batter for 6 to 7 minutes, stirring constantly to ensure that the batter doesn’t congeal at the bottom of the pan. I like to use a whisk for the first few minutes before switching to a silicone spatula. Make sure to scrape the sides and bottom of the saucepan with a spatula as you cook the batter. The batter should look like the texture of pudding.
Turn off the heat and pour the batter into the greased pan. Work as quickly as possible because the batter crusts over very easily, making it difficult to smooth out the top. Use your spatula to scrape all the batter into the pan. Then, use the spatula to smooth out the top as much as possible.
Let the chickpea tofu cool by an open window for 15 to 20 minutes before transferring to the refrigerator to chill for another hour, until the tofu sets.
To unmold the tofu, place a chopping board over the pan. Then, invert the pan and chopping board, so that the pan with the tofu is on top of the board.
Give the pan a shake or tap to unmold the chickpea tofu completely.
Cut into cubes or slices. Pan fry tofu in oil on a nonstick pan over medium-high heat. Make sure you use a good amount of oil, as the cubes can stick to the pan easily. Let the tofu pan fry for a few minutes so that a crust forms and turns golden before flipping them over. The crusty layer can get stuck to the pan easily if the tofu is not ready to be flipped. I like serving the pan-fried chickpea tofu with chili oil drizzled on top (see note 1 for directions) or seasoning it with teriyaki sauce.
Storing Chickpea Tofu: If you’re not planning on using the tofu right away, leave the tofu in the pan and cover it with plastic wrap, foil, or a lid. Try to use it within 1 or 2 days because the tofu can release quite a bit of water over time, causing the tofu to fall apart easily. Alternatively, you can freeze the tofu. Because of the high water content of the tofu, wrap the tofu in plastic wrap first before placing it into a freezer bag or container. Otherwise, a lot of ice crystals will form easily around the tofu. The tofu can be kept for a few months. Simply defrost the tofu when you want to cook it.
