Combine the flour, salt, baking powder, baking soda, sugar, and lemon zest in a bowl. Make a well in the center and add the butter, milk, eggs, vanilla and lemon juice.
Mix by hand with a wooden spoon or for no more than 1 minute with an electric mixer until all ingredients are incorporated and a sticky dough is formed.
Roll the dough, 1 tablespoon at a time, into ropes 10 inches long. Cut them in half, lay the halves side by side and intertwine them to form a twist. Form the twists into rings.
Place a piece of parchment paper on a baking sheet and arrange the rings on it. Bake for 15 minutes or until lightly browned. Remove from the oven and cool on the baking sheet.
