Mix the hot cake mix and tofu together. It's okay if it's a bit sticky.
Put the shiratamako into a separate bowl, add water and knead until it's about the same softness as your earlobes.
Mix ingredients from Step 1 and 2 and put into a piping bag. People that find it bothersome can scoop the mixture with a spoon and drop it into the oil as is. It will still taste the same.
Cut baking paper into 8cm square sheets, pipe the mixture onto the sheets. Join the ends of the mixture by wetting a finger and molding together.
Put the doughnuts in 170°C oil while still on the baking paper sheets and deep fry until golden. When the sheets come away from the doughnuts in the oil take them out.
Mix kinako and sugar and coat the doughnuts to finish.
I had a go at making ball shapes for the donuts. It was difficult to start with but it became enjoyable as I got used to it!
Apple tea cup-san who posted a review of my recipe used scissors to snip! snip! the piped mixture into segments instead of using a rubberband. You can get them looking this good with scissors Please go ahead and use this as reference as well.
Story Behind this Recipe
My friend's question of 'I wonder if we can make pan de ring?' inspired me to try and recreate that famous mister doughnut pan de ring. They turned out soft springy and delicious. They are a little hard but the shape is exactly the same as the ones in the shop and the process a lot simpler. I've also uploaded a recipe that doesn't require a piping bag.
The mixture itself is only a little sweet so if you're not going to coat the finished doughnut in sugar, add some sugar to adjust to your taste during step 1
