Prepare the Yeast: In a small bowl, dissolve a pinch of sugar into 200 ml of lukewarm water. Sprinkle the yeast on top and let it sit undisturbed for about 4 minutes. After this time, gently stir and allow it to rest for another 6 minutes until frothy and bubbly, indicating that the yeast is activated and ready.

Combine Ingredients: In a large mixing bowl, whisk together 4 cups of all-purpose flour and 1 teaspoon of salt. Create a well in the center, then pour in the frothy yeast mixture along with ¼ cup of softened unsalted butter. Stir the mixture until it starts forming a dough.

Knead the Dough: Turn the dough out onto a floured surface and knead it for about 10 minutes until smooth and elastic. Let it rise in a warm area for 40 to 60 minutes until it doubles in size.

Preheat the Oven: While your dough rises, preheat your oven to 200°C (390°F).

Shape the Muffins: Once the dough has risen, gently punch it down, divide into 12 pieces and shape each into a ball.

Prepare the Baking Soda Bath: In a large saucepan, combine 1.75 liters of hot water with 50 grams of baking soda and stir until dissolved.

Bath the Dough: Submerge each dough ball in the baking soda solution for about 15 seconds on each side and then place in greased muffin cups.

Bake the Muffins: Bake for approximately 20 minutes or until the muffins are golden brown and a toothpick inserted comes out clean.
