I've always known this craveable bread as Fergasa, but to the rest of the world it might be Green Onion Cheddar Buttermilk Bread. Whatever you call it - it's delicious!
Stir together buttermilk, yeast and 1 tsp sugar, let it sit for about 10 minutes.
Stir in slightly cooled melted butter (1/4 cup) and egg, along with 1 cup of the flour and stir until well mixed. Add in the rest of the flour, sugar and salt. Stir until the dough starts to pull away from the bowl, you may need to add a bit more flour here.
Once the dough pulls away, flour a flat surface and turn the dough out. Knead for 10 minutes adding any extra flour to keep it from getting too sticky.
Add dough to a greased bowl, turning several times to coat all sides of the dough ball. Let this rise in a draft-free space until doubled in size, About 1.5 hours.
Punch the dough down and remove to a flat surface again, roll out to about a 12x18" rectangle. Sprinkle on the cheddar cheese and green onions. From the short side, roll the dough tightly into a log shape, pinch together the seams on the bottom of the loaf and tuck the ends under. Place into a generously buttered loaf pan. Let rise for 30 minutes.
Preheat oven to 375 degrees F.
Generously butter top and sides of the loaf and bake for about 50-60 minutes. You may have to tent the bread with foil if the crust gets too brown. Once cooked, remove and brush again with more butter.
Let cool on a wire rack. Store in the refrigerator for about 5 days.
