add water yeast and sugar to the bowl and allow to rest for 5 min until the yeast starts to foam up.
add flour and salt then mix until the liquid is incorporated.
pour the dough out onto a clean dry surface then kneed until it all forms a ball.
divide the dough into 4 equal pieces then add a bit of food dye to 3 of them. I used purple, black, and orange and left one white.
starting with the while piece knead for about 10 minutes until the dough becomes stiff and smooth. then knead the orange, purple then black until the colour is well distributed and the dough is stiff.
roll each piece into long tube shapes and lay them next to each other.
twist, roll, and fold the 4 pieces together (don't knead) only slightly to marble the colours together not blend them.
place in an oil-prepared bowl, cover, and place in a warm dry place to rise for 1 hour. the dough should almost triple in size.
once the dough has risen preheat oven to 425°f
divide the dough into 8 equal pieces then turn them into balls by folding the sides into the underside of the middle and rolling the ball on the counter. then flatten slightly by pushing down with your hand.
press your finger into the middle of one of the balls and wiggle until you feel the countertop through the dough. widen the hole by rolling two fingers inside the bagel. make the whole slightly larger than you would think since it will shrink when the bagel rises during cooking.
place the bagels on a flat surface and cover to rest for 10 minutes.
fill a large pot with water and salt heavily. bring the pot to a rolling boil over high heat.
boil bagels in water for 1½ minutes being careful not to over crown the pot.
place bagels on a baking sheet lined with parchment paper or a silicone mat. leaving enough space in between so they do not touch.
bake in the oven for 20 min then transfer to a cooling rack to cool.
