How to Calculate Raw Grocery Weights from Guest PAX Count for Wedding Catering (2026)
Scientific Per-Head Grammage Standards for Indian Wedding Menus
Raw grocery requirements are calculated based on raw ingredient grammage per adult 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.
For 500 PAX with 1 paneer starter (Tandoori Paneer Tikka) and 1 main curry (Paneer Butter Masala): procure 50kg of fresh malai paneer total.
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.
Guests consume an average of 2.2 rotis/naans. For 500 PAX: procure 38kg of mixed wheat flour and maida.

| Fresh Malai Paneer | 100 grams | 20.0 kg | 50.0 kg | 100.0 kg | Moisture absorption (expands ~10%) |
| Raw Lentils (Urad / Toor Dal) | 35 grams | 7.0 kg | 17.5 kg | 35.0 kg | Expands 3.0x when slow-cooked |
| Mixed Vegetables (Cauliflower, Peas) | 120 grams | 24.0 kg | 60.0 kg | 120.0 kg | Vegetable prep trimming loss (~15%) |

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:
- 1Pure 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).
- 2Whole & Ground Aromatic Spices (8g – 12g / Guest): Budget 5kg of whole spices (cardamom, cinnamon, cloves, bay leaves, cumin, and star anise) for rich aroma.
- 3Mandi 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.

Common Operational Questions
How much raw rice should be cooked for a 500-person Indian wedding?
For 500 guests with 2 rice dishes (e.g. Jeera Rice and Dum Biryani), cook 28kg to 30kg of raw basmati rice (calculated at 55 grams per guest), which yields approximately 75kg to 85kg of cooked rice.
How much raw paneer is needed for 800 wedding guests?
For 800 guests with 1 paneer starter and 1 paneer main curry, order 80kg of fresh malai paneer (calculated at 100 grams of raw paneer per guest).
What is the standard vegetable trimming loss factor in commercial catering?
Fresh vegetables experience an average trimming and peeling loss of 15% to 20% (e.g. removing cauliflower stems, peeling potatoes, and shelling peas). Commercial procurement orders must add a 20% gross buffer over net recipe weights.
How does catering software prevent raw grocery over-purchasing?
