In a food processor with the
S blade attached, grind the sunflower seeds to a fine
meal. Add the Cheddar and salt, and pulse the processor six to
eight times to blend. Add the water, and pulse until a
dough ball forms.
Cover your cookie sheet with a piece
of baking parchment. Turn the dough out onto the
parchment, tear off another sheet of parchment, and put
it on top of the dough.
Through the top sheet of
parchment, use your hands to press the dough into as
thin and even a sheet as you can. Take the time to get
the dough quite thin-the thinner, the better, so long
as there are no holes in the dough.
Peel off the top
layer of parchment. Sprinkle a little salt over the
surface and gently press it in into place. Use a thin,
sharp, straight-bladed knife or a pizza cutter to score
the dough into squares or diamonds.
Bake for about 30
minutes. Peel off the parchment, break along the scored
lines, and let the crackers cool. Store them in a
container with a tight lid.
