In a large bowl combine the flour, sugar, baking powder, salt and honey.
Gradually add the water to the flour mixture until it forms a shaggy dough. If the dough is too dry, add water 1 tablespoon at a time. Knead the dough with your hands for a couple of minutes.
Cover the bowl with a damp towel and let the dough rest for 5 minutes.
Place the dough on a countertop and stretch and knead the dough for 5 minutes. Return the dough to the bowl and cover with a layer of plastic wrap and a damp cloth and allow to rest for several hours or overnight.
Use a kitchen scale and divide the rested dough into 10 balls.
Take a piece of dough and tuck the edges of the dough under forming a ball with a tight and smooth surface.
Liberally coat the dough balls with olive oil and set aside for 5 minutes.
Preheat your oven to 225˚F/107˚C.
Using your fingertips press the dough ball out into a disk, then use a rolling pin to roll the dough out as thin as possible. You will want to be able to see your countertop beneath the dough and the final dimensions will be about 18 in. X 18 in./46 cm. x 46 cm.
Take a tablespoon of softened butter and spread it all over the dough. Use a pastry brush to spread a layer of olive oil all well.
Fold one third of the dough on the left side to the middle of the dough, repeat with the right side and you should have a long column of dough.
Brush the pastry with olive oil. Start at the bottom and tightly roll the pastry.
Coat the inside of the jachnun tin with oil and add layer of sandwich bread. Add a layer of oiled parchment.
Place the rolled dough into the bottom of the prepared tin. Pack 5 rolls tightly next to each other in one layer. Cover the rolls with a layer of parchment and add another layer of 5 rolls.
Add a final layer of oiled parchment and top with 4 raw eggs. Cover with the lid and place in a preheated 225˚F/107˚C oven for 12 hours.
Serve the jachnun and eggs with grated tomato seasoned with salt.
