Total Appetizers = Guests x Pieces Per Person Total Main = Guests x Serving Weight

Planning Guidelines

  • Appetizer-only party: 10-12 pieces per person
  • Dinner party: 4-6 appetizers + main + sides
  • Main course: 200-280 g per person
  • Side dishes: 150-200 g per person
  • Always prepare 10-15% extra

    • Worked Example

    guests = 20apps_per_person = 8main_g = 250sides_g = 200
    1. 01Appetizers: 20 x 8 = 160 pieces.
    2. 02Main course: 20 x 250 g = 5000 g = 5 kg.
    3. 03Sides: 20 x 200 g = 4000 g = 4 kg.
