(From the archives - something cool and easy, perfect for the summer. Originally published in July 2008.)
Previously, I explained how some dishes that are not tofu are called -tofu, because of the shape, texture or both. This is the case with tamago dofu, a smooth savory egg custard that's served cold.
You can make it in a square mold, to make it look tofu-like. But I prefer to keep it a lot simpler by cooking the tamago dofu in the serving container it will be served in. This can be anything as long as it's heat-proof. Here I have used some sturdy glass cups made of pressed glass, but I've also used little pudding molds, tiny glass bowls made for holding ingredients while you're cooking, and even coffee cups.
There are very few ingredients in a tamago dofu: dashi or soup stock, eggs, and a few flavorings. Because of this, each component should be of top quality, because you'll taste each one quite clearly. Traditionally the soup component is dashi, but I don't really like the fish flavor of dashi when it's cold. So I prefer to make a simple vegetable stock instead.
Tamago dofu should be served ice cold. It's a great appetizer for a summer meal, or an interesting and soothing snack. I have been guilty of making 4 cups and 'hiding' them so I can eat them all by myself.
