When calculating how many appetizers you'll need for a party, consider:
•Time of day the party will occur--If the appetizers are in place of a meal, prepare enough to compensate (at least six to eight appetizer portions per person).
•Length of party--Increase the amount and variety of food as the time increases.
•Guests' food preferences--Are many people dieting? Any know allergies or special dietary restrictions?
•Occasion--If the guests are active, they'll probably eat more.
•Number of recipes you want to make--peple can eat more when there are more offerings.
