Preheat oven to 450 degrees F (230 degrees C). Line a baking sheet with parchment paper and set aside.
Whisk together All-Purpose Flour (2 cup), Olive Oil (1/4 cup), Sesame Seeds (1/2 tablespoon), and Achar Masala (1 1/2 tablespoon) in a large bowl. Add Salt (1/2 teaspoon) and Water (1/2 cup) and continue to mix together into a smooth dough ball. If your dough is a little dry add some more water if it's a little wet add a Tbsp of flour until you have a smooth dough ball.
Cut the dough in half and cover one piece of dough with a tea towel or plastic wrap. Take the other piece and roll it out until it is 1/16-inch thick.
Brush the top of the dough with water and sprinkle on a few extra sesame seeds.
Cut the dough into 2-inch squares and place them on the parchment-lined baking sheet about 1-inch apart. Repeat steps 3 and 4 with the other half of the dough.
Bake for 8-10 minutes or until the edges just start to brown a little. Cool the crackers on the baking sheet. Store in an airtight container for up to 3 weeks.
