Japanese Soft-Cooked Eggs (Onsen Tamago)
A perfectly poached egg inside its shell, soft-cooked eggs have a solid yolk with soft, creamy whites. In Japan, ‘Tamago’ is the word for ‘egg’, whereas ‘Onsen’ refers to the hot geothermal springs throughout the country. Those temperature-stable hot springs supply the perfect level of heat for making soft-cooked eggs. After dropping their eggs (shell-on) into the hot spring, Japanese people could leave for a few hours and come back to find the silkiest, most custardy eggs imaginable.

Recipe Notes

*** Regardless of cooking method, time is the main factor in the gelling reactions that cause egg whites and yolks to thicken and set. At 35 to 45 minutes, the whites will be softly set; the yolk will be warm but runny. At 90 minutes, the yolk will have thickened to a custardy texture. Either is good, depending on your preference!
