Combine the warm water, yeast and sugar and let stand for 5 minutes, or until foamy.
Combine the salt, flour and onion powder, then add to the water and yeast mixture. Mix and adjust flour or water if needed to make a dough that is just slightly sticky. Knead the dough until it “pushes back”, 5-10 minutes.
Put the dough in a bowl at least double its size and top with a wet cloth. Let the dough rise for about an hour until it has doubled in size.
Punch down the dough and divide into 6 pieces. Form each into a ball and poke your thumb through the center to make a bagel shape. Set the bagels in a warm place to rise about 15 minutes.
Line a baking sheet with parchment or spray with non-stick spray.
Add the baking soda and enough water to a tall frying pan or saucepan that is deep enough to float the bagels. Bring to a boil.
Set the bagels in the boiling water, 2-3 at a time and boil for 1-2 minutes on each side. Remove the bagels with a slotted spoon, drain them on a towel, and place them on the prepared baking sheet. Sprinkle with dried mined onion. Bake at 400F for 15-20 minutes until golden and cooked through.
