In large bowl, dissolve yeast and 1tbsp of sugar in the warm water. Let sit about 5 minutes
Whisk in oil into the yeast mixture
Whisk in sugar and salt
Beat in 4 eggs, one at a time
Gradually add in flour (about ½ cup at a time) until the dough holds together. Should be slightly tacky but not sticking to your hands
Turn dough onto lightly floured surface and knead until smooth
In another large bowl, coat with olive oil
Place dough in oiled bowl and cover with plastic wrap or paper towel. Let rise in warm place for 1 hour, it should double in size. Note: It can also rise in a pre-warmed oven at 150F then turned off
Punch down dough and cover and let rise again for 30 minutes
Separate the dough into two (one for each loaf). We will be working with one loaf at a time
With the dough for one loaf, split it into 6 balls and place on lightly floured surface
Roll each ball, one at a time, into a strand ~12 inches long and ~1½ inches wide
Lay all 6 strands parallel to each otherNote: You can optionally pinch the strands together at the top, not necessary because we will go back and fix the ends
Starting from the strand to the furthest right, weave it through the strands: over 2, under 1, over 2
Repeat the previous step pattern until you reach the end, it is ok to stretch the strands a bit towards the end, but do not rip them
Pinch the loose strands at the end and tuck them under the loaf
Going back to the top of the loaf (it is easier if you flip the dough so the top is facing you), finish off the braid with the same pattern and pinch the remaining loos strands and tuck them under the loaf
Place the loaf on a greased baking pan. Repeat steps 11-17 with the second loaf and place on the same baking sheet, with at least 2 inches between them
Beat one egg and using a pastry brush, brush both loaves
Let rise for one hour (or this is where you can freeze it)
Pre-heat oven to 375F
Brush loaves again with the egg wash and sprinkle on any desired toppingsNote: if using a frozen loaf, remove from freezer 5 hours before baking
Baking on middle rack for 15 minutes
Brush loaves again with the egg wash (mainly to the light areas of the bread to achieve even coloring)
Bake again on middle rack for 20-25 minutes until golden
