Dough:
3 1/4 cups unbleached all-purpose flour
1/4 cup potato flour OR 1/2 cup + 1 tablespoon dry instant
mashed potatoes (unflavored)
3 tablespoons granulated sugar
1 1/2 teaspoons instant yeast
1 1/4 teaspoons salt
3 tablespoons soft butter
1 teaspoon vanilla extract
1 large egg
1 cup + 2 tablespoons room-temperature or lukewarm milk
Filling:
1 cup peeled, grated apple (about 1 large apple, or 1 to 2
smaller apples)
1 tablespoon lemon juice
1/2 cup granulated sugar
3 tablespoons cornstarch
1/8 teaspoon salt
1 teaspoon cinnamon
Glaze:
1 cup confectioners' sugar
1 teaspoon vanilla extract
1/8 teaspoon salt
1 to 2 tablespoons water OR 2 to 4 tablespoons heavy cream
To make the dough: Whisk together all of the dry
ingredients, then add the butter, vanilla, egg, and milk, mixing until a shaggy
dough forms. If your schedule permits, let the dough rest for 30 minutes; this
resting period allows the flour to absorb the liquid fully, making it easier to
knead.
Knead the dough — by hand, using a mixer, or in a bread
machine set on the dough cycle — until it's smooth and soft, though still
slightly sticky. Place the dough in a greased bowl, turning to coat. Cover the
bowl, and let the dough rise until it's almost doubled in bulk, about 1 1/2 to
2 hours. The amount of time this takes will depend on the temperature of your
kitchen; yeast works the fastest at about 85°F, but we prefer the flavor the
bread gets from a longer, cooler (about 70°F) rise. If you're using a bread
machine set on the dough cycle, simply allow it to complete its cycle.
While the dough is rising, make the filling. Toss the grated apple with the lemon juice in
a saucepan. Whisk together the sugar, cornstarch, salt, and cinnamon, and add
to the pan, stirring to combine. Cook over low heat, stirring frequently, until
the apple starts to release its juice. Increase the heat to medium, and bring
to a simmer. Simmer, stirring, until the mixture thickens, 1 to 2 minutes;
drawing a spatula across the bottom of the pan should leave a track that
doesn't readily fill in. Remove from the heat, and set aside to cool to room
temperature; if you want to hasten the process, place in the refrigerator.
To assemble the loaf: Gently deflate the risen dough and
turn it out onto a lightly floured or greased work surface. Divide the dough in
half. Roll the first half into a 10" x 12" rectangle. Spread half the
filling over the rolled-out dough, leaving a 1/2" margin clear of filling
along all sides.
Starting with a long side, roll the dough into a log,
sealing the edge. Use a bench knife, pizza cutter, or sharp knife to cut the
log in half lengthwise. Place the half-logs, filled side up, side by side on a
well-greased or parchment-lined baking sheet. Keeping the filling side up,
twist or "braid" the two logs together, working from the center to
each end. Pinch the ends together. Repeat with the second piece of dough. Cover
the twists lightly, and set them aside to rise for 1 to 2 hours; they should be
puffy but not doubled in bulk.
To bake the bread: Bake the loaves in a preheated 350°F oven
for 30 to 40 minutes, until they're lightly browned. Check the loaves after 20
minutes and tent with aluminum foil if they're browning too quickly. When the
loaves are fully baked, a digital thermometer inserted into a loaf (be sure to
position the thermometer in the bread, not the filling) should register about 190°F.
Remove the bread from the oven and allow it to cool for about 1 hour before
glazing and serving.
To make the glaze: Mix together all of the glaze
ingredients. Drizzle over the loaves once they're cool.
Store leftover bread, loosely covered, at room temperature
for several days; freeze for longer storage. If you know ahead of time you're
going to freeze one or both of the loaves, don't glaze; wrap completely cooled,
unglazed bread tightly in plastic, and freeze for up to a month. When ready to
serve, remove from the freezer, unwrap, cover loosely with plastic, and let
thaw at room temperature. Glaze and serve.

Notes:
If you don't have potato flour or flakes, substitute 3/4 cup
(about 6 ounces) unseasoned mashed potatoes, adding them to the dry ingredients
along with the milk. Reduce the milk to 2/3 cup, adding additional flour or
milk as needed to create a smooth, soft dough.
Want to prepare this loaf ahead, then bake it the next day?
Make the bread up to the point where it's shaped and on a pan. Cover the loaves
with lightly greased plastic wrap, and refrigerate overnight (about 12 hours).
Next morning, remove the loaves from the fridge, and let them come to room
temperature and rise a bit (still covered); this will take 1 to 2 hours,
depending on the warmth of your kitchen. Bake and finish as directed.
To make apple swirl rolls: Follow the directions above to
the point where you've rolled the dough into a log. Repeat with the remaining
piece of dough, then cut each log into 1" slices. Place the slices cut
side up in well-greased or parchment-lined pans, placing them close together
(though not touching) for soft-sided rolls, or about 2" apart for crustier
rolls. Allow the rolls to rise until they're puffy. Bake as directed, reducing
the baking time to 18 to 20 minutes. Drizzle with glaze.
