Preheat oven to 375° with a rack set in lower third of oven. Lightly spray with cooking oil an 8, 9 or 10-inch round cast-iron skillet, spring-form or round baking pan; set aside.
In a small bowl, add apple cider vinegar to 1/2 cup of milk and set aside to curdle. If it is necessary to add more milk to the dough later, simply add additional un-curdled milk.
In a large bowl, whisk together the gfJules™ flour, sugar, baking powder, baking soda, and salt.
Using a pastry cutter or a paddle attachment on a stand mixer, cut the butter into the bowl with the flour mixture until a fine pebbly meal is made. Add yogurt, curdled milk, raisins and seeds (if using) and beat until a sticky dough is formed. If the dough is dry or at all crumbly, add more milk (up to ¼ cup) and mix until the dough holds together well and resembles scone dough – sticky, thick and slightly wet.
Scoop dough into prepared skillet or pan, then flour your hands well with gfJules™ flour and pat the dough to form it into a mound in the center of the pan, or use a bench scraper, if you prefer. Dip a large, sharp knife in water, then score an "X" into the center of the mounded dough.
Bake until golden brown and a toothpick or skewer inserted into the center down to the bottom comes out clean, about 1 hour. If the top begins to brown too quickly, loosely cover with a piece of aluminum foil. NOTE: if making in an 8 or 9-inch pan, it may be necessary to bake longer for the entire loaf to cook through, so cover with aluminum foil after one hour to prevent over-browning.
Once fully cooked, transfer to a wire rack to cool before slicing.
Yield: 1 loaf
