For centuries, Sephardic women have been baking a bread called the the Siete Cielos in honor of Shavuot. In Ladino Siete Cielos means the seven heavens. This refers to a teaching about how the seven celestial spheres opened up when G-d gave the Torah on Mount Sinai. Ladino is a blend of Hebrew and Spanish which was the language of the Jews of Turkey, Greece, and parts of Morroco.

Here’s a picture.
I discovered this Challah from Nicholas Stavroulakis’s wonderful “cookbook of the Jews of Greece.” He drew a lovely picture and offered instructions which I attempted to copy.
The orb at the center which is roughly the size of a smallish Challah represents Mount Sinai . Around it are seven rings-made from ropes of dough-to represent the seven heavens (sheva rakiyim in Hebrew). On top of them are small dough sculptures representing Miriams well, the 10 Commandments, an open Torah scroll, a dove ( a symbol of the Jewish people) and Moses’ copper serpent (nachas nehoset).

This is what it looked like when I took it out of the oven.
