This is wonderful and you're going to love making this and sharing it with those you love.
You can make these loaves one at a time or both at once. My recipe for each loaf is:
500g of starter (preferably fed the evening before you use it)
275g of water
500g of flour (any mixture of flours you want)
20g salt (non-iodized)
30 minute autolyse
5 minutes of slap and fold
3 stretch and folds (separated by 10 minute rests)
4 hour bulk ferment
stretch and fold
2 hour final bulk ferment (in a floured proofing basket - top side down)
preheat oven to 500 degrees
bake in covered Dutch oven at 500 degrees for 20 minutes
uncover and bake an additional 30 minutes at 450 degrees
Enjoy!!!
