In the bowl of your food processor equipped with a dough hook, pour the crumbled yeast with the warm milk and water. Leave for 10 minutes.Add the flour, salt and chopped butter.Start to turn on slow speed and then increase little by little to a medium speed. Let the dough knead until it becomes smooth and soft, about 10 minutes.If you don't have a food processor, this can be done by hand but it will take a little longer. Strain your bowl and let it sit at room temperature (or near a radiator, or in your oven with a bowl of hot water on the bottom and the door slightly ajar) until the dough doubles in size. This may take 1 to 2 hours.
Flour your clean work surface and divide the dough into 10 equal portions and shape the pretzels. Place them on a baking sheet covered with baking paper and let them rest for at least 30 minutes, covered with a clean and dry cloth.
Preheat your oven to 200°C.
In a large saucepan, boil water with salt and baking soda. Poke the little balls of dough one by one for 30 seconds.Drain well and place on a baking sheet lined with baking paper, spacing them well apart. Sprinkle a little coarse salt or gomasio on top.Bake for 20 minutes until the pretzel buns are golden brown.Let cool on a wire rack and eat immediately, it's a treat!
