Process sugar and 2 tbsp tarragon until well blended into a pale green mixture.
Measure out 1/4 cup tarragon sugar and mix with dry yeast and water. Let yeast bloom for about twenty minutes.
Blend milk with remaining 3 tbsp tarragon. Then mix milk and egg into yeast mixture.
Mix remaining ingredients together and add liquid mixture. Using a stand mixer with dough hook, mix until dough pulls clean off edges. Alternately, mix with a wooden spoon.
Place dough in a well oiled bowl covered with a clean towel to rise in a warm place for at least 2 hours.
Roll out dough to 1/2 in thickness. Cut into small rectangles using a pizza cutter. Let dough rise for another 45 minutes in a warm place.
Brush with oil then with milk and bake at 350 for 9-12 minutes.
