Step 1: Prepare the Dough

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a medium bowl, whisk together almond flour, tapioca flour, xanthan gum, baking powder, salt, and any optional seasonings.
3. In a food processor, pulse the cheddar cheese and butter until crumbly. Add the egg yolk and dry mixture, pulsing until the dough starts to come together. Add water one tablespoon at a time, as needed, to form a soft dough.

Step 2: Roll and Cut

1. Place the dough between two sheets of parchment paper. Roll it out to about ⅛-inch thickness.
2. Use a small fish-shaped cookie cutter (or any shape you like) to cut out the crackers. Gather scraps, re-roll, and cut until all dough is used.

Step 3: Bake

1. Transfer the shaped crackers to the prepared baking sheet, leaving a small space between each.
2. Bake for 10–12 minutes or until the edges are golden and crisp. Keep a close eye on them to avoid burning.
3. Let the crackers cool completely on the baking sheet before enjoying.
