How many kilos of pork to prepare for 100 guests when having a party?

It's impossible to give an exact number of kilos of pork for 100 guests without more information. Here's why:

* Serving size: Are you planning on serving pork as a main course, a side dish, or part of a buffet? How much will each person eat?

* Other food: What other dishes are you serving? If you have a variety of other options, people might eat less pork.

* Pork cuts: Different cuts of pork have different yields. For example, a whole roast will yield more edible meat than a rack of ribs.

* Guest preferences: Are your guests heavy meat eaters, or are they more likely to opt for vegetarian or other options?

Here's a general guideline:

* Main course with no other meat: Plan for around 200-250 grams of pork per person.

* Main course with other meat: Plan for around 150-200 grams of pork per person.

* Side dish: Plan for around 100 grams of pork per person.

To get a more accurate estimate:

1. Consider your menu: Look at the overall meal and how much pork you think guests will eat.

2. Check the yield of the cut: Find out what percentage of the pork is edible after cooking.

3. Adjust your calculations: Take into account any other factors, such as guest preferences or the availability of other dishes.

For example:

If you are serving a roast pork loin as a main course with other meat, you might need 150 grams per person. A 5kg pork loin would yield about 3kg of edible meat, which would be enough for 20 people. To feed 100 people, you'd need around 15kg of pork loin.

Remember: It's always better to overestimate than underestimate. You can always freeze any leftover pork for later use.
