This depends only on your preferences; for example you can use 6-8 lbs.
To start with, you should never be putting mustard or vinegar in potato salad!! Yuck!!
Unless you have a recipe which substitutes the mayonnaise with something much healthier, then no...
For a potato salad serving 100 people, a general guideline is to use about 1 cup of mayonnaise for every 5 pounds of potatoes. Therefore, with 25 pounds of potatoes, you would need approximately 5 cups of mayonnaise. Adjust the amount based on personal taste and desired creaminess.
A cup of potato salad typically contains about 3 to 5 grams of protein, depending on the ingredients used. If the salad includes additions like eggs, bacon, or protein-rich dressings, the protein content may be higher. The base ingredients like potatoes and mayonnaise contribute less protein compared to other components. Always check the specific recipe or nutrition label for precise values.
Approximately 4.5 quarts in 5 pounds of potato salad, including hard-cooked eggs.
That is 87.5 pounds
I would make 25 pounds of it.
A bound salad is a salad made of hearty ingredients (meat, potatoes, etc.) fortified with a thick sauce (almost always mayonnaise). This is the kind of salad you'd make into a sandwich or eat with a main course; think tuna or potato salad.A dressed salad is a "normal" green salad served with some kind of salad dressing. These dressings (Ranch, Thousand Island, vinaigrettes) are usually made with mayonnaise or oil, but are used in a much lower quantity than in a bound salad.
That depends on the recipe you use.
Depends what else you put into it. I would make about 130 pounds of salad from 100 pounds potato as I add eggs, onion, bell peppers etc.
Generally speaking, 5 lbs of potato salad will fee 30 people. 12 people would be a little over half of that, so around 2.5 lbs of potato salad.
I would add more potatoes. or chuck it.
