Preheat the oven to 400 degrees F.
Mill your wheat berries on the finest setting of your grain mill.
In a food processor, combine the flour and salt.
Add in the oil and pulse until the oil is mixed in the flour. You are looking for coarse crumbs.
Warm your water to 95-100 degrees F.
With the food processor running, drizzle in the warm water until a cohesive ball of dough comes together.
You are looking for ball of dough that is not dry and crumbly, but also not so moist that it is hard to work with.
Take 2 pieces of parchment paper and spritz a little bit of oil on each. Spread the oil around to cover the entire side of the paper.Turn the dough onto one of the pieces of parchment paper, oil side up. Place the other piece of parchment paper on top of the dough, oil side down. Roll out the dough with a rolling pin as thinly and evenly as possible, aiming to cover the entire piece of parchment paper.
Remove the top piece of parchment paper and transfer the piece with the cracker dough over onto the baking sheet.
Score the crackers with a pizza cutter into the size squares you prefer. Top with coarse sea salt.
Bake in the preheated oven for 12-15 minutes or until the crackers are lightly golden brown on the edges.
Allow the crackers to cool before breaking apart and storing.
