Menachot 94 - The Twelve Breads of Vision
The two loaves on Shavuot were kneaded one by one and baked one by one, but the twelve breads of vision, brought every Shabbat, were kneaded one by one and baked in pairs. The reason for separate kneading is so that every loaf would get its correct amount of flour.
The breads of vision were baked in a mold and then transferred to another golden mold. Baking in a mold was required because of the breads' special shape: according to Rabbi Chanina, they were shaped like an open box, and according to Rabbi Yochanan, they were shaped like a small fast boat dancing on the waves.
