Matcha Bread Chiffon Roll

There are four primary polyphenols in green tea and they are often collectively referred to as catechins. Powerful antioxidants, catechins have been shown in recent studies to fight viruses, slow aging, and have a beneficial effect on health. Clinical tests have shown that catechins destroy free radicals and have far-reaching positive effects on the entire body. Free radicals are highly reactive molecules and fragments of molecules that can damage the body at the cellular level leaving the body susceptible to cancer, heart disease and other degenerative diseases.

Dough	Chiffon Cake
350 g All-purpose flour 15 g Motcha tea powder 55 g Sugar 1/2 tsp Salt 6 g Instant dry yeast 40 g Whole Egg 20 g Honey 120 g Warm milk 110 g Tangzhong Starter - Water Roux Starter via Starch Gelatinization 50 g Butter	3 Egg yolks 25 g Sugar 60 g Milk 40 g Vegetable oil 1/2 tsp Vanilla extract 100 g Cake flour 1/2 tsp Baking powder 4 Egg whites 75 g Sugar A few drops white vinegar

1. To prepare the bread dough. Sift together the flour, tea powder, sugar, salt and instant dry yeast in a mixing bowl. Add in egg, honey, milk and the starter. Mix with dough hook at slow speed for 1 minute. Increase the speed to the medium and continue to knead until a dough forms. Adjust the speed to slow and cut in butter. Stir until all incorporated. Increase the speed to medium again and knead until the gluten has developed, i. e. elastic, smooth, non-sticky and leave from sides of mixing bowl. Prove the dough in a lightly greased plastic bag for 1 hour, leave in a warm place until dough doubles in volume.
2. Punch the dough down to release gases produced in the fermenting process. Divide them into 4 portions and round up. Rest, covered, for 15 minutes at the room temperature.
3. To prepare the chiffon cake. Beat the egg yolk with sugar until the sugar completely dissolved. In another bowl, stir together the milk, oil, and vanilla extract. Warm the mixture to 35C/95F. Add into the egg yolk mixture. Sift the cake flour and baking powder into the liquid mixture.
4. Whip the egg whites on high speed until foamy. Add the white vinegar and continue beating until soft peaks form. Beat in the sugar and beat until stiff peaks form. Gently fold 1/3 of the whites into the batter to lighten it, and then fold in the rest of the whites. Pour the batter into 2 Swiss roll pan each lined with a baking sheet, spreading the cake batter with an offset spatula. Bake in a preheated oven 165C/340F for 10-12 minutes until gold brown. A toothpick inserted in the center will come out clean and the cake, when lightly pressed, will spring back.
5. Immediately upon removing the cake from the oven carefully remove the parchment paper. If the baking paper sticks to the cake, lightly brush the back of the paper with a little warm water, allow to stand for a few moments, then peel the paper from the cake. Each cut into half and set aside. Roll the each bread dough out with a rolling pin to about 15 x 12 cm.
6. Set the cake atop the dough and roll up from a short side. Place them on the baking pan lined with a baking sheet. Cover with a wet towel and leave to rise for about 1 hour until doubled in bulk. Preheat oven to 175C/350F and bake the bread for 20-25 minutes.
