Dissolve 2 tablespoons baking yeast and 6 tablespoons sugar in 2 cups warm water. Add 2 cups unbleached white flour, beating it in with a whisk. Let rise as a sponge for about 10 minutes. Beat in 1/2 cup oil, 2 teaspoon salt and about 4 more cups flour (use a whisk until it gets too thick - then just use a spoon).
Turn dough out on a floured board and knead for about 10 minutes. Add only enough flour on the board to prevent sticking. The dough should be soft but not sticky. Roll lumps of dough between your hand and the work table into rolls 3/4 inch x 8 inches (0.7 x 20 centimeters). Take one end of a roll and wrap around your first two fingers into bagel shape, sealing the two ends by rolling them together between your fingers and worktable to make a smooth seam. Let rise 5 minutes on a well floured board. Repeat until you have about 30 bagels.
Have ready a 4 liter (4 quart) pot two thirds full of boiling water. Add 1/3 cup sugar. Drop 4 or 5 bagels into the rapidly boiling water, risen side down, and put on a lid. Boil 30 seconds on one side then 30 seconds on the other, keeping a rapid boil all the time. Remove bagels with a slotted spatula and place about 1/2 inch / 7 millimeters apart on a well-oiled cookie sheet. Bake at 180C/375F for 25-30 minutes or until golden brown.
