Tamahimo Oyakodon Recipe

たまひも親子丼 Tamahimo Oyakodon

Unlaid chicken eggs made into oyakodon.

This post follows my previous post on the traditional Oyakodon and is a variation on it using tamahimo eggs (たまひも), kinkan (キンカン) or chochin (lantern/ 提灯) eggs. These eggs are the eggs that are harvested from the hen when the hen is slaughtered. This means that they have yet to be fertilised and are at various stages of development. Those further along the developmental pathway would have egg white and an almost fully formed egg shell, while eggs at an earlier part of the pathway are basically just egg yolks alone, growing from small sizes initially all the way to a full sized yolk. These yet to be fully develop eggs also do not have an egg white attached to them, and are basically egg yolks with a firm layer around them. This means that they can be handled and pressed without bursting, unlike typical egg yolks which break easily. The taste of these eggs are like that of a concentrated duck egg yolk, with a much richer and sweeter mouth feel and bright orange colour compared to conventional egg yolks.

Unlaid chicken eggs sold in Japan, known as Tamahimo.

They are almost impossible to find all around the world except in Japan. Even in Japan, they are usually found in high end Yakitori (chicken BBQ) restaurants and served as a treat. They can also be pre-ordered from a butcher and are usually served with a Fallopian tube. At a Yakitori restaurant, the fallopian tubes by which the eggs are attached too are skewered on a bamboo stick along with pieces of chicken meat and liver and grilled over charcoal. The egg itself is only lightly grilled and typically allowed to hand off the side of the grill to prevent it from being overcooked.

The Fallopian tube themselves however, are usually pre-cooked to ensure that they are not too tough. These eggs are also a part of traditional Jewish cuisine and are known as eyerlekh. Here, they were traditionally cured or poached in chicken soup but are now almost never consumed due to how hard it is to obtain them. The recipe that follows is Tamahimo Oyakodon, which is extremely luxurious considering how many eggs they contain, and is also a recipe that will be impossible to make because of how hard it is to obtain these eggs and it’s more rather to see what is possible with this ingredients.
