The ketuba is written before the wedding but is not finished until just before the signing, when one or a few last words are filled in.  The ketuba is signed by two kosher witnesses after tanayim.  

Even though foods manufactured and sold in the USA are required to list their ingredients, a simple reading of ingredients may not be sufficient to determine the kosher status of some foods because:

• They are not required to list “manufacturing aids” such as oil, and
• The manufacturing equipment may be non-kosher.

 

WERE BOTH FOOD AND UTENSIL LESS THAN 120° F?
YES
What to Do Wash off with cold water and soap.
Status Everything is kosher and may be used immediately.
 
NO
WAS THE UTENSIL CLEAN AND UNUSED at 120° F or more FOR MORE THAN 24 HOURS?
Note Clean means no residual food, including pareve; this IS essential since the food or utensil or both were hot! If used at 120° F or more for pareve within 24 hours, ask a rabbi.
YES
Status

• Food is kosher
• Utensil requires kashering. 

What to Do

• Wash utensil with cold water and soap.
• Wait 24 hours after the spill occurred before kashering it.

Note If you wash off the utensil with hot (above 120° F) water, you must wait 24 hours after cleaning the utensil before kashering it.
 
NO
IS THE SPILLED FOOD LESS THAN 1/60th of the volume of the commonly used capacity of the utensil (if the utensil is empty) OR less than 1/60th of the actual volume of food contained within the utensil?
YES
Status

• Food is non-kosher.
• Utensil is kosher.

What to Do Wash utensil with cold water and soap and wait 24 hours before using the utensil.
Note If utensil had food in it and the spilled food was less than 1/60th of the volume of the food in the utensil, you may use the utensil immediately after cleaning it and you need not wait 24 hours.
 
NO (Spilled food was 120° F or more, utensil not clean, utensil used within 24 hours, spilled food is more than 1/60th of the utensil's volume)
Status

• Food is non-kosher.
• Utensil is non-kosher.

What to Do Utensil must be kashered.  See Hag'ala/Boiling or Libun/Direct Heat for instructions on how to kasher each material.



Note In this section, meat spilled onto a dairy utensil and dairy spilled onto a meat utensil are treated the same.

Blood spots even from unfertilized eggs may not be eaten; the custom is not to eat that entire egg. Blood spots in fertilized eggs render the entire egg non-kosher.
 

Cold, spicy/charif, solid food (with no liquid) does not transfer gender UNLESS it was under pressure, so simply sitting in an opposite-gender or non-kosher container does not have any effect.

     Cold, spicy/charif, solid food (with no liquid) does not transfer gender UNLESS it was under pressure, so simply sitting in an opposite-gender or non-kosher container does not have any effect.
Note You may l'chatchila eat spicy/charif food if it is on a glass plate, even if it is under pressure,
     Cold, spicy/charif, liquid food is kosher only if it sat less time than needed to become cooked.
Example
     You ate cold (less than 120° F, or 49° C) spicy/charif food of one gender on a cold plate of the opposite gender:
Solid Food
      If the cold, spicy/charif food is solid, the food is kosher l'chatchila. But you should only do this ad hoc and you should not eat it with a fork.
Liquid Food
      If the cold spicy/charif food is liquid but it is in contact with a utensil of the opposite gender for less time than it takes to boil, it would be kosher but, again, you should only do this ad hoc.

The purpose of the rabbi at a wedding is to ensure that the extremely detailed wedding halachot, as set out by the Shulchan Aruch, are followed correctly. If not, the wedding might not be kosher.
 
A Jewish marriage includes: a written document (ketuba); a financial transaction (ring) in front of two kosher witnesses; and physical intimacy. 
 
Witnesses
 

• The witnesses must be shomer Shabbat Jewish men.
• The bride and groom should confirm verbally that these are the two (and the only two) witnesses that they want.  

 
Ring

• The groom must confirm that he acquired and owns the ring.
• The groom must say Harei at mekudeshet li ...  to the bride and place the ring on her (index) finger.

 
Ketuba

• The ketuba must be kosher.
• Before the chuppa, someone (anyone, including women) must fill in (no safrut is required for this):  the Hebrew names of the bride and groom; the date the wedding is taking place; the wedding location (city, etc.); and that a kinyan was made.
• The ketuba must be signed by two kosher witnesses.

All beverages that contain alcohol made from any of the five grains (wheat, barley, oats, rye, and spelt), and which were owned by a Jew during the Passover holiday, are not kosher.

Rabbinic guidance is recommended when using a river, lake, or spring as a mikva due to:

• Problems of mud, dirt, or sand, and
• Difficulty in checking if the person is fully underwater,
• It might not be a kosher mikva.

Food soaked in brine, vinegar, or any spicy liquid for long enough to be cooked if heated on a burner or in an oven will absorb or transfer gender or non-kosher status from/to any utensil used with it.

You may microwave a dairy food in a meat (or meat food in a dairy) glass (or Pyrex or Corelle) utensil. Even if the food gets hotter than 120 degrees, the food and utensil are still both kosher. (This is not true if placed in a conventional oven!)

Pot lids are treated as if they are utensils.

A non-spicy/non-charif liquid or food with any liquid (enough to pour, but that may be even one drop) that sits for 24 hours or more will transfer gender or non-kosher status to its container.
Situation Dairy or meat liquid-containing food is in pareve container.
StatusContainer will become dairy or meat (regardless of intention).
