The Table of Shewbread, or the Table of the Presence לחם הפנים held twelve loaves of bread set apart to be eaten only by the Levite Priests.  On top of the loaves were bowls of Frankencense to burn on the Altar of Incense.  

So what was the recipe for the holy bread? 

Short answer: It has been lost or kept secret.
Eli Saidel, a Jewish baker who lives in Israel, whom I've spoken with, was entranced by the holy bread and set out on a journey to find out exactly how it was made. He said,
“They had to be prepared and baked quickly because they were unleavened, like matzah.
Each loaf weighed 3 to 4 Kilograms (6.614 to
8.818 LBS according to some opinions, and as much as seven kilos (15.45LBS) according to others.  Now that's a heavy loaf!
According to tradition, the Garmu family managed the baking process, ensuring that the bread was prepared properly. The work of baking, preparing and removing the showbread from the ovens required great skill, and the Garmu clan kept their trade secrets within the family.


SPIRITUAL INSIGHT

When tempted in the wilderness by Satan to turn stones into bread, Jesus answered and the words of Deuteronomy 8:3, “It is written: ‘Man shall not live on bread alone, but on every word that comes from the mouth of God.”
Again in John 6:35 “...Jesus declared, “I am the bread of life. Whoever comes to me will never go hungry…”
Jesus has given us himself as our daily bread, to know him and the Father so that we can find joy and peace in Him.
