Step 1

Preheat the oven to 300 degrees F and cover a large 11 X 17-inch baking sheet with a piece of parchment paper.  Lower the oven rack to the lowest setting.

Step 2

Add all dry ingredients to a large mixing bowl.  Mix together with a whisk to get any clumps in the flaxseed meal out.

Step 3

Add boiling water and melted butter. Mix together with a spatula until a dough forms.  Test for saltiness and add more salt if desired.

Step 4

Use spatula to spread out the dough thinly on the parchment-covered baking sheet.  It should cover the baking sheet completely from edge to edge and be about 1/4 inch thick.

Step 5

Bake on lower rack for 1 hour, checking occasionally to make sure it’s not burning.  Turn the baking sheet around halfway through so that it cooks evenly.  Pay attention as seeds are heat sensitive.

Step 6

Turn off the oven and let the crackers dry in the oven for another hour.

Step 7

Break into pieces.
