01 - Preheat oven to 325°F and line a baking sheet with parchment paper.
02 - In a large mixing bowl, combine all seeds, sea salt, and garlic powder. Stir until evenly distributed.
03 - Pour in the water and stir thoroughly. Let the mixture rest for 10 minutes until it thickens and forms a gel-like consistency.
04 - Spread the mixture evenly onto the prepared baking sheet, pressing down firmly with a spatula to create a thin, uniform layer about ⅛ inch thick.
05 - Bake for 30 minutes until the surface is set and beginning to dry.
06 - Remove from the oven and score the sheet into cracker shapes using a knife or pizza cutter. Return to the oven and bake for another 10 to 15 minutes until golden brown and crisp.
07 - Cool completely on the baking sheet, then break into individual crackers along the scored lines.
