mix the flour, yeast, and salt together in the bowl of a stand mixer
add 3/4 of the warm water
run the mixer with the kneading hook until the dough just starts to come together
then pour in the remaining water and the olive oil
let the mixer knead the dough on low for about 5 minutes until the dough is soft and pliable, if while you're mixing you see the dough is very soft you can add another 1-4 TBSP of flour to the dough
once the dough is soft and silky smooth add a little oil to the bowl and turn the dough to coat it
cover and let the dough double in size
line a large baking sheet with parchment paper, set aside
once it's double gently knead the air out of the dough
weigh the dough and divide it into 7 equal pieces, if you don't have a scale divide as best you can, cover the dough piece to keep them from drying out
take one piece of dough and roll it into one long strand, about 22 inches in length, cover the strand with plastic wrap or foil
repeat with the remaining pieces of dough
lay the 7 strands of dough on a clean counter or table
about halfway down the strands divide the dough and lay three strands to the left of you, and the remaining four to the right, with a big space between them,
working from the midldle of the strands take the farthest right strand and cross it over the three pieces and lay it the middle angled to the left
then take the dough on the far left and cross over the three strands of dough (including the one you just put there from the right) into the middle of the dough angled to the right
repeat with all the strands until you get to the end, you will have half of the braid done
pinch the ends of the dough together
the gather the braid in one hand, the strands in the other and flip the WHOLE THING over, putting the braid away from you, and the strands towards you
make sure the strands are not tangled
beginning again on the right take the far right of the strands and bring it to the middle angled towards the left
take the far left strand and bring it over the three strands on the left (including the one you just put there from the right)
repeat with strands until you come to the end, pinch the dough together
trim off each end straight
bring the two ends together and fix the dough to the corresponding strands as best you can, it won't be perfect, adjust the wreath so it's as even as possible
cover the pan and let the wreath almost doubled in size
preheat the oven to 425°
beat the egg with a spalsh of water until mostly smooth
when ready to bake remove the cover from the wreath
use a pastry brush to paint the wreath with egg the wash
bake at 425° for 25 minutes or until the the bread sounds hollow when thumped on the bottom
cool, slice, enjoy!
