Preheat oven to 300 °

Place all ingredients into a bowl, mix well.

Let mix sit for a few minutes until thickened a bit. Meanwhile lay out some parchment paper onto two baking sheets.

With a large flexible spatula, spread the mixture thinly onto the parchment paper, using the edges of the baking sheets to create a square edge. Try to avoid holes in your mixture but work to get the seeds very thin.

Bake for 1 hour, turning the pans occasionally for even browning. At the 1 hour mark take the pans out of the oven and with a pizza cutter or sharp knife cut the crackers into squares. You want the mix to still be a bit moist and flexible when you do this. Return to the oven for an additional 20 - 30 minutes until crisp and lightly browned.

Remove to a rack and let cool. Break along cut lines.
