I topped the crackers with paprika, but I think I would just use some coarse sea salt in the future. Also, I would like to try this recipe again with sesame or pumpkin seeds in place of the flax and sunflower seeds, which were just what I happened to have on hand.
Sunflower Butter Crackers
1/4 cup flax seeds, ground
1/4 cup sunflower seeds, ground
1/2 cup white spelt flour
1/2 cup dark rye flour
1/2 teaspoon salt
1 tablespoon unrefined sugar
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon ground coriander
4 tablespoons chilled butter, cut into pieces
3 tablespoons buttermilk
Grind the flax seeds and sunflower seeds in a food processor or blender until ground. Add the ground seeds to a medium bowl and add the rest of the dry ingredients and mix well.
Work in the butter with your fingers until well incorporated.
Bake 7-10 minutes until lightly browned on edges. Cool on a rack.
