Pineywoods has given you the same numbers I use. LanceR is also correct on the way to look at the food. There is no set formula in catering events. Believe me after over 20 years of catering I have never had 2 parties the same. So we do an average and usually plan a bit heavy.
They both have given you very good methods to follow. It really depends on what you have going on the day before and the time of the food service on how I would proceed.
If after lunch time I would be more likely to follow Pineywoods method. If around lunch time I would lean towards LanceR method, but I would do the oven at 200 degrees and put the pork in just before i went to bed. That way when I woke up it would be ready. I set it at 200 so it does not get over cooked....done this many times and works great. I place the pork in a pan with some beer, apple juice concentrate and a it of apple cider vinegar. Wrap with plastic then foil, no the plastic will not melt. When i get up in the morning I remove the pork from the pan and use the juices to make my finishing sauce.
Below is some information I posted on another thread.....
You have received a lot of info on processes for the cooling, reheating and storage. It is very important to be aware of the temperatures and how long you are in them. I use and most people use the range of 40-140 for the TDZ (Temperature Danger Zone)(USDA is 41-135). As pointed out bacteria grows best in the TDZ range. When cooling you want to go from 140 to below 40 in less than 6hrs according to the 2009 USDA Guidelines, I try to go a lot faster than that by placing into smaller amounts as suggested. I will actually place in the freezer if i don't have an ice bath handy. When reheating you again want to go as fast as you can through the TDZ, <40 to >165 in <2hrs. Below are my preferred methods:
- For small amounts: In a saute pan with a little finishing sauce and or BBQ sauce. Very quick and effective.
- For medium to large amounts: In a shallow pan with a small amount of finishing sauce covered with plastic wrap then foil in a 325 degrees oven till it reaches 165 degrees. You can add the BBQ sauce after.
- Crock Pot: not really my first choice due to time in the TDZ can be longer than wanted. I will saute and place into the crock pot for hot holding if needed. Others have and continue to get great success from this, just not my first choice.
- Boiling in the bag: Works very well. Need to make sure you have a towel or something to buffer the plastic bag from the bottom of the pan. This method is used in commercial application a lot. I don't do this at home due to not wanting to wait for water to boil, but at work we do this a lot.
If you are going to store your PP either in the fridge or freezer, do not add a finishing sauce to it with a high acid content. This will cause to meat to break down over time and get a mushy texture. I also will intentionally only cook my meat to 195 and allow to rest before pulling. This way it will maintain a better texture in my opinion. I don't like shredded or mushy pork. I like to see the chunks of the bark and pork.
