Oven preheated to 375 °F and pizza stone ready, process cooked wild rice in a food processor or blender until it becomes a sticky mess. Add sweet rice flour, salt, and sesame oil to mix and gradually add water until the dough forms. Divide sesame seeds into the dough, cover with cling film, and let rest for 20 minutes.
Cut parchment paper into squares slightly larger than the size of the cookie (ours were about 4 inches by 4 inches). Take 11/2 teaspoon of the dough, place it between two pieces of parchment paper, and roll with a rolling pin to make it thin - 5 sheets of paper thickness and around 4-5 inches in diameter. Peel off the parchment paper on top, set aside, and roll out more crackers.
Place as many of the crackers with parchment paper onto the heated pizza stone in batches and bake for 4-6 minutes until they start to become crispy around the edges. Carefully remove each cracker from the pizza stone and transfer it to a cooling rack.
Peel off the parchment paper and place the crackers back in the oven on the opposite side to bake for another 4-6 minutes or until crispy. Once cooled off, serve with a side of ginger miso sauce or cheese!
Smaller crackers can also be made with one sheet of parchment paper and 1/4 - 1/2 teaspoon of dough at one time. The process is the same, except they will be about only 1.5 inches in size. Delicious and simple!
