In a mixing bowl, combine warm water, brown sugar, and yeast; let sit for 5 minutes until frothy.

Gradually add flour and salt, mixing until combined. Knead on a floured surface for about 5 minutes until smooth.

Place the dough in a greased bowl, cover with a damp cloth, and let rise in a warm spot for about 1 hour or until doubled.

Preheat oven to 425°F (220°C). Punch down the risen dough and divide into bite-sized pieces. Shape each piece into knots or balls.

Boil water in a large pot; add baking soda carefully. Boil each pretzel bite for 30 seconds before removing them with a slotted spoon.

Arrange boiled bites on parchment-lined baking sheet. Brush with melted butter and sprinkle with coarse salt.

Bake for 12-15 minutes until golden brown.

Serve warm with dipping sauces of your choice.
