Whisk together the cooled tangzhong (water roux) with milk and honey until smooth and then set aside briefly.
In the bowl of a stand mixer, combine dry ingredients (flours, yeast, salt and nut meal). Then add in the tangzhong mixture. Using the dough hook attachment, mix at low speed until a dough starts to form.
Rest the mixture in the bowl for 10 minutes before progressing (this should help the flour absorb the liquids). Knead the mixture on medium speed for 5 minutes or until it creates a soft but firm dough that bounces back to the touch.
Transfer the dough to a lightly oiled bowl. Cover with a clean tea towel and set aside in a warm place until doubled in size, between 1-2 hours.
Gently knock the air bubbles out of the dough and transfer them to a work surface.
Divide the dough into three equal portions (you can use scales to measure these out accurately). Form each piece into a ball, cover and leave to rest for a further 15 minutes.
Flatten out one piece of dough into an oval shape. Starting from the short edge, roll the dough into a log. Then repeat with the other two pieces.
Place dough, seam side down into a lightly greased loaf tin (20cm x 12cm), making sure to leave a little space between them. Set aside to rise in a warm place for a further 1-2 hours. Halfway through the rising process, preheat your oven to 170°C.
Bake for 30 minutes, or until golden brown and the internal temperature is 82°C
Remove from the oven and allow to cool completely before slicing.
