Homemade Sourdough Pretzels from Scratch

I just couldn't wait to share this recipe with everyone. We've had our sourdough mothers and starters for a while now, and it's time to expand it's use beyond the regular bread you've been making.
I think it's safe to say almost everyone like a good pretzel, and they're even better when made fresh. You can even pick what toppings to put on, allowing for your own personal take on a pretzel.
I hope you enjoy this recipe, and let me know in the comments how yours turned out, and what kind of toppings you tried out.
Ingredients needed:
2 tbsp butter
1 cup milk
4 cups flours
1 1/2 cups sourdough starter
2 tbsp sugar
1 tsp salt
1 tbsp baking soda
pretzel toppings of your choice
