Can you calculate it from the recipes you are using? It it makes enough
for 8 servings multiply it out?
Or are you purchasing.
I was just at the store and on a 2# container of potato salad, they said 6 servings. Same for 2# macaroni salad.
It's a nice chart, but 4-1/2 quarts of potato salad to feed 25...my recipe just says
It makes 4 servings and that's with 2 lbs potatoes...which also doesn't help because it doesn't say what a serving size is. I thin I'm just going to make 4 recipes (8 lbs potatoes) and double the pasta salad which means 1 lb uncooked pasta - but it also has chicken, lettuce and tomatoes in it.
Your pasta recipe only serves 4--and I know it has chicken in it, but it is
serving size that matters, I think. Maybe just take a look at another pasta salad recipe (that doesn't have chicken) and see what kind of number of servings it will make.
As for the 4.5 qts for 25--if that is a 6oz. serving by weight (4.5 qts=144oz.), that is about right. I think that would be about a half cup (by volume) serving.
I think it is this kind of calculation you will need. ;o)
And you may wish to consider sitting the bowl of pasta in a slightly bigger bowl of ice if
the pasta and/or potato salads are going to sit out for any length of time, especially if they are mayonnaise-based (particularly homemade mayo) and/or protein-based. Just a food safety thing for these hot days of summer.
I'm not a scientist, but I have heard that mayonnaise is almost never the culprit of food poisening
simply because it contains vinegar and lemon. Here is a link that explains the science behind this.
It is always smart to take precautions with any food that is served outdoors, and it should never sit more than two hours.
I had a catered event two years ago, it was summer and very warm outside. My caterer instructed me to move the food indoors after two hours, because the ice would be melted anyway and it was the safe thing to do. People were still picking at the food and I asked everyone to assist in the move. It was rather fun, and everyone dug in again, inside the house.
