I recommend using a Ziploc brand container If you don't have any, you can line a microwave-safe container with parchment paper.
First, the okara. If you're using the powdered type, the resulting amount when reconstituted varies by the brand and manufacturer, but the overall weight should come to about 50 g. I recommend reconstituting with soy milk.
Add the ingredients to the okara in the order listed from the top.
For the soy milk, first add 50 g. Stir it in and if it still seems a bit dry, add 10-20 g more.
After adding the soy milk, it should be a creamy texture.
Place in the microwave, uncovered, and microwave for 7 minutes at 500 W. Once done, remove from the container and wrap it in a towel to cool.
Cut into any shape you want. The top photo shows how it looks cut into 10 slices.
Story Behind this Recipe
When I only used soy flour, the texture was off, so I combined it with some okara.
