Food waste is money you already spent. Most owners know they throw away some rice at night or some tomatoes that went soft, but few know the number. Once you put a rupee figure on it, the waste stops looking small.
This guide is for owners and head cooks who want a plan they can start this week, without new equipment. It works for a karahi house in Lahore, a biryani point in Karachi or a café in Islamabad.
Step 1: Measure before you fix anything
You cannot reduce what you do not measure. For two weeks, keep a waste log next to the main bin. A notebook works. Every time something is thrown away, someone writes:
- Date and time
- Item and quantity (weigh it if you can, or count pieces)
- Reason: spoiled, overcooked, dropped, returned by customer, leftover at closing
- Initials of the person throwing it away
At the end of each week, convert the log into rupees using your purchase prices. Here is an example from a mid-sized restaurant after one month of logging:
| Waste item | Typical amount | Cost per unit | Monthly cost |
|---|---|---|---|
| Cooked rice left at closing | 2.5 kg per day | Rs 180 per kg cooked | Rs 13,500 (30 days) |
| Naan dough balls not used | 40 pieces per day | Rs 12 per piece | Rs 14,400 (30 days) |
| Chicken spoiled or trimmed badly | 1.5 kg per week | Rs 750 per kg | Rs 4,500 (4 weeks) |
| Total | Rs 32,400 |
That is Rs 32,400 a month from just three items, close to the monthly salary of an extra kitchen helper. In most kitchens, a few items like these make up most of the waste, so start with your top three.
Step 2: Find out why it happens
Waste falls into a few groups, and each has a different fix:
| Type of waste | Common cause | Main fix |
|---|---|---|
| Overproduction | Cooking or preparing more than you sell | Prep to par levels based on sales |
| Spoilage | Poor storage, old stock used last | FIFO and proper labelling |
| Preparation waste | Bad trimming, careless peeling | Training and standard cuts |
| Plate waste | Portions too big, dish not liked | Review portion sizes and menu |
| Mistakes | Wrong order cooked, dish burnt | Clear kitchen tickets, slower rush handling |
Step 3: Prep to par levels
Overproduction is the biggest source of waste in most Pakistani kitchens, especially with rice, gravies and dough. The fix is a par level: the amount of each prepared item you need for a normal service, based on what you actually sell.
Look at your sales for the same day over the last four weeks. If you sold 62, 58, 66 and 64 plates of biryani on Thursdays, the average is (62 + 58 + 66 + 64) ÷ 4 = 62.5 plates. Set Thursday's par at about 65 plates, and cook a second smaller batch only if the first runs low. Cooking in two batches costs a little more effort and saves a lot of rice.
- Set separate pars for weekdays, Fridays and weekends.
- Adjust for Ramzan, Eid, wedding season and cricket match days.
- Make dough in two rounds on slow days instead of one large batch.
Step 4: Store with FIFO
FIFO means first in, first out. The oldest stock gets used first. In a kitchen this comes down to simple habits:
- Label every container with the date it was made or received. Masking tape and a marker are enough.
- When new stock arrives, move older stock to the front of the shelf or fridge.
- Keep raw chicken and mutton on the lowest fridge shelf, away from cooked food.
- Check the freezer and fridge temperature daily, and more often during load-shedding.
- Buy tomatoes, coriander and other fast-spoiling vegetables in smaller, more frequent lots.
Step 5: Fix portions and recipes
If customers often leave half the rice on the plate, your portion may be too big. Watch what comes back to the dishwashing area for a week. Reducing a rice portion by 50 grams across 60 plates a day saves 3 kg of rice every day.
A written recipe card for each dish, with weights for the main ingredients, keeps portions the same no matter which cook is on shift. It also keeps your food cost predictable. Our guide on food cost percentage shows how portion size feeds straight into your margins.
Step 6: Use what you can, safely
Some leftovers can be used the next day, if they are stored correctly and your food safety standards allow it. Examples:
- Trimmings from chicken boneless prep can go into a staff meal or a soup base on the same day.
- Stale bread can become croutons or bread pudding in a café.
- Overripe fruit can go into shakes on the same day.
Never reuse anything that has been on a customer's plate, and never keep cooked rice or chicken unrefrigerated overnight. A food poisoning complaint costs far more than the food you saved.
Protect cold storage during load-shedding
Long power cuts in summer can spoil a freezer full of chicken and mutton in one afternoon. If your generator or UPS cannot run the freezers for long, keep the doors shut during outages, avoid buying large meat stocks just before announced load-shedding hours, and move the most valuable stock into the freezer that stays on backup power. Write the freezer temperature in your log before and after each long outage.
Check deliveries at the door
Some waste arrives with the supplier. Soft tomatoes, wet onions or chicken that smells wrong should go back with the delivery boy, not into your store. Weigh meat and vegetables when they arrive and compare them with the slip. A supplier who regularly sends 9.5 kg on a 10 kg slip is costing you 5% on that item before your cook touches it. Record the actual weight received, so these gaps show up in your stock figures.
Step 7: Make it a weekly routine
Waste reduction fails when it becomes a one-time campaign. Set a 15-minute meeting every week with your head cook:
- Read the week's waste log total in rupees.
- Pick the top item and agree on one change.
- Check last week's change: did it work?
Compare your waste with your stock usage too. If your count shows more chicken used than your sales explain, and the waste log does not account for it, the problem is somewhere else, such as portions or missing stock. A regular inventory count makes this comparison possible.
Where software helps
Paper logs work, but software makes the numbers easier to see. When recipes are linked to stock, the system knows how much chicken your sales should have used, and you can compare that with what you bought and counted. ArfaPOS records kitchen and store inventory with recipe-linked deductions, which is described on the restaurant inventory software page.
Start small. One waste log, one par level for your biggest item and one weekly meeting will show results within a month.
