Preheat oven to 350ºF. Meanwhile combine the flaxseeds and water in a medium-sized bowl. Mix together and let it sit for about 10 minutes. The flaxseeds will absorb the water and form a thick gel-like mixture, this is what holds the crackers together.
Mix in the seeds. Add the rest of the seeds as well as the sea salt to the bowl and stir until combined.
Spread and bake. Line a medium-sized sheet pan with parchment paper and spread the seed mixture in an even layer to cover the entire pan. Aim for a thickness of about one centimetre for best results. Then bake at 350ºF for about 60 minutes.
Cool and enjoy. Once the seed crackers are finished baking, allow them to cool completely. Then break the seed crackers into pieces and enjoy them on their own or with some hummus or guacamole!
Notes
For thinner crackers: Spread the mixture out onto a large baking sheet and baking for half the time, keeping a close eye to make sure your crackers don’t burn.
To make even sized crackers (optional): To get even sized crackers, remove your crackers from the oven halfway through the baking time and quickly score/cut your crackers into squares using a knife or pizza cutter.
