01 - Dissolve yeast in lukewarm milk with 1 tablespoon sugar. Let stand 5-10 minutes until foamy and activated.
02 - In a large mixing bowl, whisk together flour, remaining sugar, salt, and lemon zest until evenly blended.
03 - Pour yeast mixture, melted butter, eggs, and vanilla into dry ingredients. Mix until a soft, sticky dough forms.
04 - Knead dough by hand on a floured surface or with a stand mixer using a dough hook for 8-10 minutes until smooth and elastic.
05 - Place dough in a greased bowl, cover with plastic wrap or a towel, and let rise in a warm spot until doubled, about 1 to 1.5 hours.
06 - Punch down risen dough. Divide into three equal portions. Roll each into a 20-inch rope, tapering ends slightly.
07 - Braid the three ropes together tightly. Shape braid into a circle, pinching ends together to seal. Transfer to a parchment-lined baking sheet.
08 - Gently press dyed raw eggs into the braid at even intervals, nestling them securely into the dough folds.
09 - Cover loosely with a towel and let rise for 30-45 minutes until puffy and slightly expanded.
10 - Preheat oven to 350°F. Brush dough surface with milk, avoiding the eggs. Sprinkle with sugar if desired for extra sweetness.
11 - Bake for 25-30 minutes until deep golden brown and hollow-sounding when tapped. Eggs will cook completely during baking.
12 - Transfer wreath to a wire rack. Cool completely before slicing. Serve warm or at room temperature.
