2/3 cup warm water
1 tsp active dry yeast
1 tsp sugar
2 cups all-purpose flour
1 tsp salt
2 tbs plain yogurt
¼ cup vegetable oil, plus more to oil grill
1 tbs minced garlic
In a large bowl, whisk together warm water, yeast and sugar until yeast is dissolved. Set aside in a warm place for 10 minutes for yeast to proof.
In another large bowl, sift together flour and salt three times. Add to yeast mixture, along with yogurt and 2 tbs of the vegetable oil. Mix with a fork to bring ingredients together, then turn out onto a lightly-floured surface and knead for about 5 minutes until dough is smooth and elastic. Place dough in a large oiled bowl, cover with plastic wrap and set aside in a warm place to rise for 90 minutes, until doubled in bulk.
Punch down dough and knead for about 5 minutes. Divide into sixths and roll each out into 8-inch rounds. Combine remaining oil with minced garlic.
Preheat and lightly oil grill. Brush one side of each naan with garlic oil and place 2-3 at a time, oiled side down, on hot grill surface. Cook 2-3 minutes, until puffy and lightly-browned. Brush uncooked side with more garlic oil and turn over to finish cooking. Repeat with remaining naans.
