You cannot reduce what you do not measure. Most kitchens underestimate wastage because it disappears into the bin one small portion at a time.
Step 1: Log every item thrown away
Record the date, item, quantity, reason and station. A cheap kitchen scale makes this accurate. Convert quantities to rupees using cost per unit - wastage in rupees gets attention that kilograms never do.
Step 2: Group by reason
- Spoilage / expiry - ordering or rotation problem.
- Over-production - forecasting and batch size problem.
- Prep trim and peel - yield and knife-skill problem.
- Plate waste - portion size or quality problem.
- Cooking errors - training or equipment problem.
Step 3: Fix the top three items
In most kitchens a small number of items cause most of the waste - often cooked rice, gravies, breads and expensive proteins. Focus on them first: smaller batches cooked closer to service, better FIFO, revised par levels, standard portions.
Tip: Set a target as a percentage of food purchases and review it weekly with the team. Celebrate improvement - wastage logging must never feel like punishment, or entries stop.
Step 4: Use leftovers safely - or not at all
Re-using food is only acceptable when it was cooled, stored and reheated within safe limits. When in doubt, throw it out - and log it, so tomorrow's batch is smaller.
