1. Place the barley flakes in a bowl or in the bucket of a bread machine and pour the boiling water over them. Cool to lukewarm, about 20 minutes, and stir in the remaining ingredients, except the apples.
2. Stir, then knead to make a soft, slightly sticky dough (or allow to go through the dough cycle of a bread machine). If you’re kneading by hand and the dough is very sticky, allow it to rest for 15 minutes before adding more flour.
3. Add the apples and cinnamon bites at the end of the kneading process, or when indicated by the bread machine.
4. Let the dough rise, covered, for 1 hour, until it''s puffy.
5. Turn the dough out onto a lightly greased work surface, knead gently, then form into a loaf or ball. Place on a greased or parchment-lined baking sheet, or in a greased 9" x 5" loaf pan. Cover and let rise till almost doubled in bulk, 1 to 1 1/2 hours.
6. Preheat the oven to 400°F while dough is rising. Bake the bread for 35 to 40 minutes, until it's deep brown and sounds hollow when thumped on the bottom. An instant-read thermometer inserted into the center of the loaf will register 205°F.
7. Remove it from the oven, cool in the pan for 10 minutes, then turn it out of the pan onto a rack to cool completely.
