Warm the milk to just below boiling, then add the honeybush. Steep 5 minutes, then strain and let cool to lukewarm. Add it, butter, yeast, and sugar to a bowl and whisk to combine. Add flour, cardamom, and salt, then knead. Raise 1 hour. Punch down, divide into 1. Shape into rounds, cover and raise 30 more minutes. Make a dent with a shot glass, brush with egg, then fill the dent with jam. Bake at 400 for 12-16 minutes. Enjoy!
