Combine Dry Ingredients: In a medium-sized mixing bowl, add the almond flour, lupin flour, psyllium husk powder, xanthan gum, salt, and any other optional seasonings. Whisk them together thoroughly to ensure everything is evenly distributed. This step is crucial for the dough’s consistency.

Form the Dough: Add the avocado oil and the hot water to the dry ingredients. Using a spatula, immediately begin mixing everything together. The mixture will quickly thicken and pull away from the sides of the bowl, forming a cohesive dough ball. Knead it with your hands for about 30 seconds in the bowl until it’s smooth and uniform.

Roll the Dough: Place the dough ball between two large sheets of parchment paper. This is the key to rolling it out without any sticking. Using a rolling pin, roll the dough out as thinly and evenly as you possibly can. Aim for a thickness of about 1/16-inch or less—the thinner the dough, the crispier the chip.

Cut the Chips: Peel off the top layer of parchment paper. Using a pizza cutter or a sharp knife, cut the rolled-out dough into classic triangle shapes. You can also cut them into squares or rectangles for crackers.

Prepare for Cooking: Gently separate the cut triangles and arrange them in a single layer. You have two options for cooking:

• For Baking (Recommended for large batches): Preheat your oven to 350°F (175°C). Slide the entire bottom sheet of parchment paper with the spaced-out chips onto a large baking sheet. Sprinkle the tops lightly with additional sea salt.

• For Air Frying (Recommended for extra crispiness): Preheat your air fryer to 350°F (175°C). Carefully place the chips in the air fryer basket in a single layer, ensuring they don’t overlap. You will need to cook in batches. Sprinkle with salt.

Cook to Perfection:

• Baking Method: Bake for 12-16 minutes, or until the edges are golden brown and the chips feel firm to the touch. Keep a close eye on them after the 10-minute mark, as they can go from golden to burnt very quickly.

• Air Fryer Method: Air fry for 5-8 minutes, flipping or shaking the basket halfway through, until golden and crisp. Air fryer times can vary, so check them frequently.

Cool for the Crunch: This is the most important step! Transfer the hot chips to a wire cooling rack. They will continue to crisp up significantly as they cool down to room temperature. Do not skip this step! The final, satisfying crunch develops during the cooling process
