Dissolve the yeast in a small bowl with a bit of warm (not hot) water and add 1/2 teaspoon of sugar. Let it sit for about 15 minutes until it becomes foamy.

In a large mixing bowl, combine the flour, powdered milk, sugar, salt, sesame seeds, and anise.

Pour in the melted butter and rub it into the dry ingredients with your fingers until well incorporated.

Add the foamy yeast mixture, beaten egg, lukewarm milk, and orange blossom water to the flour mixture. Stir to combine, then knead for several minutes until you have a soft, smooth dough.

Shape the dough into a ball and place it in a lightly oiled bowl. Cover the bowl with cling film and a clean tea towel. Allow the dough to rise in a warm spot for 1-2 hours, or until it has doubled in size.

Punch down the dough to release any air bubbles. Oil your hands and divide the dough into 8-10 equal balls, about the size of a tangerine.

Arrange the dough balls on a baking sheet lined with parchment paper. Cover with a clean cloth and let them rise again for about 30 minutes.

Preheat the oven to 180°C (350°F). In a small bowl, whisk together the egg, a pinch of instant coffee, and a pinch of vanilla.

Brush the surface of each bun with the egg glaze, then sprinkle with pearl sugar. Bake for 20 minutes, or until the buns are golden and fragrant.

Remove from the oven and let the Krachel cool on a wire rack. Enjoy warm or at room temperature with a cup of tea or coffee.
