In a small bowl, mix the 60 ml lukewarm water and yeast.
In a medium bowl, add the 300 ml hot water, honey, and butter, and stir until butter is melted.
In a large bowl, add both flours and the salt and stir. Add the yeast mixture and the honey/butter mixture and mix until a dough starts to form. Turn out onto a lightly floured surface and knead until smooth and elastic, about 10 minutes.
Transfer dough to a lightly oiled bowl and turn to coat all over. Cover and leave to rise until doubled in size, which will take about an hour, maybe a little more.
Lightly grease a 9 x 5 inch loaf tin.
Tip the dough onto a lightly floured surface and gently push down, just to get out any large air bubbles. Form the dough into a square shape about the same length as the loaf tin, then roll up so you have a loaf that fits nicely in your tin. Place the shaped dough, seam side down, in the loaf tin. Cover and leave in a warm place for about an hour, or until dough has nearly doubled in size.
Towards the end of the rising time, start preheating the oven to 375°F (200°C).
Bake the bread for 35-40 minutes, or until golden brown and the bottom of the loaf sounds hollow when tapped. When bread has finished baking, turn out onto a wire rack and let cool before cutting.
