360g all-purpose flour, plus more for shaping
2 tsp kosher salt
1 tsp sugar
1 packet active dry yeast
1.5 cup mixed green & black olives
375ml warm water
1 large shallot
1 tsp finely chopped fresh rosemary leaves
coarse sea salt
Place flour, kosher salt, sugar and yeast into a large bowl and whisk to combine. Make a well in the flour mixture. Slice olives and
place in the well. Pour warm water into the well and stir until a rough, shaggy dough forms. Cover the bowl and let the dough rise in a warm place until doubled in bulk and bubbly, 6 to 8 hours or overnight in the fridge.
Finely chop shallot. Chop until you have 1 tablespoon finely chopped fresh rosemary leaves. Lightly flour a piece of parchment paper and turn the dough out onto it.
Sprinkle the dough with the shallot and rosemary. Fold the dough over onto itself 4 times to incorporate the add ins.
Flip the dough over and quickly shape into a round ball. Cover with a towel and let rise until nearly doubled in size, 1 to 1 1/2 hours.
About 30 minutes before the dough is ready, arrange a rack in the middle of the oven and remove any racks above it. Place a large Dutch oven and its lid on the rack and heat the oven to 450F/220C.
Remove the Dutch oven from the oven. Use the parchment paper as a sling and carefully transfer the loaf, still on the parchment, into the Dutch oven. If desired, slash or cut the top of the dough with kitchen shears or a sharp knife. Sprinkle with coarse sea salt.
Cover the Dutch oven, place it back in the oven, and bake for 30 minutes. Uncover and bake until the top is browned and firm to tap, about 15 minutes more.
Remove the Dutch oven from the oven and use the parchment paper to transfer the bread to a wire rack. Cool at least 15 minutes before slicing the bread.
