Just Add Vinegar. Few People Know This Secret! My Grandmother Taught Me This

Activate the Yeast: Begin by warming the milk slightly and combining it with sugar, salt, and the egg in a large mixing bowl. Stir in the yeast and let the mixture sit for about 15 minutes. You’ll know the yeast is active when it becomes frothy and bubbly, a sign that it’s ready to work its magic.
Create the Dough Base: Pour the flour into a separate, spacious bowl, making a well in the center. Pour the yeast mixture into this well, and gently mix with a spatula until it starts to come together. You should have a sticky, somewhat rough dough.
Knead in the Butter: Turn the dough out onto a lightly floured surface and begin kneading. Gradually incorporate 40 grams of cubed butter into the dough, kneading until it’s smooth and no longer sticky. This step is crucial for developing the dough’s structure and ensuring a light, airy texture.
The Secret Ingredient: Here’s where the magic happens. Flatten the dough slightly and evenly sprinkle the vinegar over its surface. Knead the dough again, making sure the vinegar is thoroughly mixed in. This step is the secret to achieving that delightful fluffiness and tender crumb.
First Rise: Lightly oil a large bowl and place the dough inside, turning it once to coat it with oil. Cover the bowl with plastic wrap and let it rise in a warm place for about 30 minutes. The dough should double in size, indicating that it’s ready for the next stage.
Shape the Rolls: Once the dough has risen, turn it out onto a lightly floured surface. Roll it out into a rectangular shape, spread the remaining butter evenly over the surface, and fold it to create layers. Cut the dough into strips, then shape each strip into rolls or rings, depending on your preference.
Second Rise: Arrange the rolls on a baking tray, ensuring they are evenly spaced. Cover them and let them rise for an additional 15 minutes. This final rise will ensure your rolls are as fluffy and airy as possible.
Bake to Perfection: Preheat your oven to 180°C. Brush the tops of the rolls with a beaten egg yolk and sprinkle them with poppy seeds for a beautiful finish. Bake for about 30 minutes, or until the rolls are golden brown and have a lovely, crispy top.
Conclusion :

By incorporating vinegar into your roll-making process, you unlock a world of flavor and texture that’s both nostalgic and innovative.
