Activate the yeast: Combine the warm water, sugar, active dry yeast, and 1 tablespoon flour in a large bowl. Whisk until combined and let stand for about 10 minutes, until foamy.
Add the remaining liquids: Add the warm milk, oil, and salt to the activated yeast mixture and stir to combine.
Make the dough: Add 3 cups of flour and begin mixing. Gradually add additional flour as needed until a soft, slightly tacky dough forms.
Knead the dough: Knead until smooth, soft, and elastic. Avoid adding too much flour, as the dough should remain soft and pliable.
First rise: Cover the bowl tightly with plastic wrap and place a clean kitchen towel over the top. Let the dough rise in a warm place for about 1 hour, or until doubled in size.
Divide the dough: Transfer the risen dough to a lightly oiled work surface without kneading it again. Divide into 15 equal pieces and shape each piece into a ball.
Shape the crescents: Stretch each dough ball slightly, then roll it into a long, thin oval with a rolling pin. Starting from one narrow end, roll tightly toward the opposite end. Place seam-side down and gently curve the ends into a crescent shape.
Second rise: Arrange the shaped rolls on a parchment-lined baking sheet. Cover with a clean kitchen towel and let rise for 10-15 minutes, until slightly puffy.
Brush and top: Mix the water and oil in a small bowl. Gently brush the tops of the rolls, then sprinkle with sesame, poppy, flax, or your preferred seeds.
Bake: Bake in a preheated 340°F (170°C) oven for about 20 minutes, or until risen and evenly golden brown.
Cool and serve: Transfer the rolls to a wire rack and allow them to cool for a few minutes. Serve warm or at room temperature.
