Activate the Yeast: In a small bowl, mix a pinch of sugar with 200 ml of lukewarm water. Sprinkle a packet of yeast on top, stir gently, and let sit for about 10 minutes until frothy.

Prepare the Dough: In a large bowl, combine 500 g of all-purpose flour and 1 tsp of salt. Create a well, add the yeast mixture and 50 g of butter, then mix until shaggy.

Knead the Dough: Transfer the dough to a floured surface and knead for 5-10 minutes until smooth. Let rise in a warm area for 40-60 minutes until doubled in size.

Shape the Muffins: Preheat oven to 200°C. Punch down the dough, divide into 12 pieces, roll into balls, and place in muffin liners.

Prepare the Boiling Solution: In a pot, bring 1.75 liters of water to a near boil and stir in 50 g of baking soda.

Boil the Muffins: Gently lower each muffin into boiling water for 30 seconds, flipping halfway. Remove with a slotted spoon.

Bake the Muffins: Sprinkle coarse salt over muffins, then bake for 20 minutes until golden brown.
