Scientific Per-Head Grammage Standards for Indian Wedding Menus

Raw grocery requirements are calculated based on raw ingredient grammage per adult guest:

1Basmati Rice (Biryani & Pulao — 50g to 60g Raw / Guest):

Raw aged basmati rice absorbs water and expands to 2.5x to 3.0x its dry weight when cooked. For 500 PAX with 2 rice dishes (Jeera Rice + Dum Biryani), procure 28kg to 30kg of dry basmati rice, yielding ~75kg of cooked rice.

2Fresh Malai Paneer (90g to 110g Raw / Guest):

For 500 PAX with 1 paneer starter (Tandoori Paneer Tikka) and 1 main curry (Paneer Butter Masala): procure 50kg of fresh malai paneer total.

3Lentils / Dal (30g to 35g Dry / Guest):

Whole black urad dal and rajma expand to 3.0x cooked volume. For 500 PAX Dal Makhani: 17.5kg of dry lentils yields over 52kg of rich cooked dal.

4Flour / Atta & Maida (70g to 85g / Guest):

Guests consume an average of 2.2 rotis/naans. For 500 PAX: procure 38kg of mixed wheat flour and maida.

Factoring Cooking Shrinkage & Preparation Trimming Losses

Raw grocery procurement must account for culinary yield losses:

  • Vegetable Peeling & Trimming Loss: Fresh cauliflower, green peas in pods, and bottle gourd experience 15% to 25% peeling waste. Always order gross mandi weights factoring trimming loss.
  • Boneless Poultry & Mutton Shrinkage: Raw meat loses 22% to 28% weight during high-temperature tandoor roasting and braising. To serve 100g cooked meat, procure 135g of raw meat.
  • Dairy Freshness & Staggered Cooking: Procure fresh paneer within 24 hours of the event to prevent souring.

Managing Ghee, Spices & Edible Oil Grammage Ratios

tempering and cooking fat calculations for 500-PAX wedding curries:

  1. 1
    Pure Desi Ghee & Cooking Oil (35g – 45g / Guest): For 500 PAX, budget 20kg of total cooking fat (12kg refined oil for deep frying + 8kg pure cow ghee for dal tempering and sweet preparation).
  1. 2
    Whole & Ground Aromatic Spices (8g – 12g / Guest): Budget 5kg of whole spices (cardamom, cinnamon, cloves, bay leaves, cumin, and star anise) for rich aroma.
  1. 3
    Mandi Bulk Pack Sizing: Convert calculated weights into standard commercial packaging (e.g. 15kg oil tins, 25kg flour sacks, 50kg rice bags) to maximize wholesale mandi discounts.

Managing Fresh Produce Procurement & Mandi Wastage Buffers

Wholesale fresh vegetable and dairy procurement guidelines:

  • Seasonal Mandi Fluctuation Buffers: Add a 5% to 8% buffer on fresh leafy greens and tomatoes to account for transit bruising.
  • Same-Day Paneer & Dairy Sourcing: Fresh malai paneer and heavy cream must be delivered within 12 hours of the event to ensure optimum texture and taste.
  • Venura Consolidated Grocery Engine: Aggregates grocery requirements across multiple simultaneous weekend events into a single bulk order.
