In a bowl, mix warm water, brown sugar, and yeast; let it sit for about 5 minutes until foamy.
Add flour and salt to the yeast mixture. Stir until a dough forms, then knead for 5 minutes until smooth.
Let the dough rise in a warm area for about 1 hour, or until it doubles in size.
Preheat your oven to 450°F (232°C); boil water with baking soda. Shape the dough into small bites, boil them for 30 seconds, then place on a baking sheet.
Brush with melted butter and sprinkle with coarse sea salt before baking.
Bake for 12-15 minutes until golden brown.
Notes
Serve warm with mustard or cheese dip for best flavor.
