Whisk warm water, yeast, and sugar together in the bowl of your stand mixer fitted with a paddle or dough hook attachment. (If you do not have a stand mixer, just use a regular large mixing bowl.) Cover yeast mixture and allow to sit for 5 minutes or until foamy on top.
Add cannabis salt, melted cannabutter, and 3 cups (375g) of flour. Beat on low speed for 1 minute, scrape down the sides of the bowl with a rubber spatula if needed, then add 3/4 cup (95g) of flour. Beat on low speed until the dough comes together and pulls away from the sides of the bowl, about 2 minutes. If dough is extremely sticky after 1 minute of mixing, add remaining 1/4 cup of flour and continue to beat for 1 more minute.
Knead the dough: Keep the dough in the mixer and beat on low speed for an additional 2 minutes or knead by hand on a lightly floured surface for 2 minutes. Cover lightly with a towel and allow to rest for 10-30 minutes.Line 2 baking sheets with parchment paper or silicone baking mats. Silicone baking mats are highly recommended over parchment paper. If using parchment paper, lightly spray with nonstick spray or grease with butter. Set aside. Shape: With a sharp knife, pizza cutter, or bench scraper, cut dough into 6 equal pieces Sprinkle work surface very lightly with flour. Roll each piece of dough into a 20-inch rope. If the ropes keep shrinking and stretching the dough becomes difficult, stop what you’re doing, lightly cover all of the dough, and let it rest for 10 minutes so the gluten can relax. Then, return to rolling it into ropes. Cut each rope into 1.5 – 2 inch pieces to make bites. Baking Soda Bath: Mix water and baking soda together in a large pot. Bring to a boil. Place 8-10 pretzel bites into the boiling water for a quick 10-15 seconds. (Any longer and your pretzels could take on a metallic taste.) Using a slotted spatula or spoon, lift the pretzel bites out of the water and allow as much of the excess water to drip off.
Place bites onto prepared baking sheets. Sprinkle each with coarse sea salt or more Cannabis salt while they are still wet. Repeat baking soda bath with remaining pretzel bites. Bake for 15 minutes or until golden brown. Remove from the oven and serve warm.
