Mill your wheat berries on the fine setting of your grain mill.
Warm the milk or water slightly in a small saucepan.
In the bowl of a stand mixer with a dough hook attachment, add the warm milk or water, oil, and sourdough starter.
Mix until combined.
Add the flour and the salt. Mix on speed 1 until combined into a cohesive ball of dough that is soft.
Turn the mixer on speed 2 and knead for 8-10 minutes until the dough is glossy and stretchy.
Place the dough in a lightly greased bowl and cover with plastic wrap or a food grade plastic bowl cover.
Let rise in a warm spot for 8-12 hours or overnight.
The next morning or just before you shape the knots, combine the softened butter and garlic in a small bowl.
Turn the dough onto a lightly floured or oiled surface.
Roll out the dough into a rectangle that is 1/4-1/2 inch thick.
Spread the dough with the garlic butter reserving a small amount to spread on them when they come out of the oven.
Using a pizza cutter, cut this rectangle into 18 pieces. These do not have to be exactly the same size.
Next, take on of the pieces and twist it before tying it into a knot.
Place the shaped knots on a parchment lined baking sheet and cover with plastic wrap.
Let rise for 1-2 hours.
After 1 hour, preheat the oven to 375 degrees F.
Bake the knots in the preheated oven for 12-15 minutes until golden brown.
Let the garlic knots cool completely on a wire rack before storing.
