Method
Make the filling
- In a small saucepan, stir together the blueberries, sugar, cornstarch, and lemon juice; cook over medium heat for 5–8 minutes, stirring and lightly mashing the berries, until thick and jammy.
- Remove the filling from the heat and stir in the almond extract. Cool completely.
Make the dough
- Whisk the warm milk, yeast, and 1 teaspoon of the sugar; let stand for 5 minutes, until foamy.
- Whisk in the eggs, remaining sugar, and almond extract.
- Stir in the flour and salt until a shaggy dough forms.
- Knead in the softened butter a tablespoon at a time, then knead for 8–10 minutes by hand or with a stand mixer fitted with a dough hook, until the dough is smooth and elastic.
- Place the dough in a lightly greased bowl, cover, and let rise in a warm place for 1–1 1/2 hours, until doubled in size.
Assemble and bake
- Line a large baking sheet with parchment paper.
- Turn the dough onto a lightly floured surface and roll it into a 12-by-18-inch rectangle.
- Spread the cooled filling over the dough, leaving a 1/2-inch border on all sides.
- Roll the dough tightly from one long side into an 18-inch log and pinch the seam closed.
- With a sharp knife, cut the log in half lengthwise, leaving the top inch joined.
- Turn the cut sides upward and twist the two strands together, then bring the ends together to form a wreath and pinch them to seal.
- Transfer the wreath to the prepared baking sheet and cover loosely.
- Let rise for 30–45 minutes, until puffy.
- Heat the oven to 350°F.
- Whisk the egg with the water and brush it over the dough.
- Sprinkle with the sliced almonds.
- Bake for 25–32 minutes, until deeply golden and the dough is cooked through; if the almonds brown too quickly, tent the wreath loosely with foil.
- Let the wreath cool on the baking sheet for 20 minutes.
Make the glaze
- Whisk the powdered sugar, milk, and almond extract until smooth.
- Drizzle the glaze over the cooled wreath.
Notes
For the cleanest slices, let the wreath cool completely before glazing. Store covered at room temperature for up to 2 days or refrigerate for up to 5 days; freeze the unglazed wreath for up to 2 months. Plant-based milk and butter can be used for a dairy-free swap.
