Activate the yeast: In a large mixing bowl, stir the yeast into warm water with a wooden spoon. Add the sugar and oil, then let it sit for 5 minutes until it becomes foamy and bubbly.
Make the dough: Stir in the beaten egg and salt. Add the flour, one cup at a time, until you have a shaggy dough.
Knead: Turn the dough out onto a lightly floured surface. Knead for 3 to 5 minutes until smooth and elastic. Cover with a towel and let it rest for 10 minutes to relax the gluten. Knead again for another 3 to 5 minutes.
Shape the pretzel bites: Divide the dough into six portions. Roll each portion into a long rope, like playing with clay as a kid. Cut the ropes into bite-sized pieces, keeping them similar in size so they cook evenly. Place on a floured baking sheet to prevent sticking.
Boil the bites: Bring 12 cups of water to a rolling boil in a large pot. Carefully add the baking soda since it will foam up. Drop the pretzel bites in, a few at a time, for 30 to 60 seconds. Remove with a slotted spoon and place them on a parchment-lined baking sheet, spaced apart.
Top and bake: Brush each bite generously with melted butter and sprinkle with flaky salt. Bake on the middle rack at 400°F for 15 to 20 minutes, until golden brown.
Enjoy: Let cool slightly before diving in. Be warned, these bites vanish fast.
