Onsen Tamago means hot spring eggs in Japanese. Traditionally it is prepared by slowly cooking the eggs in the hot spring water to create silky egg whites and custard-like yolk. With the use of an immersion circulator or sous-vide machine, it is very easy to prepare this at home with excellent consistency!
6 Tbsp Water
1½ Tbsp Light Soy Sauce
1 Tbsp Mirin
1 Tsp White Sugar
¼ Tsp Dashi Granules
