Do
- Assemble sandwiches with ingredients straight from the fridge, and chill them immediately.
- Wrap or pack each item and label it with the date and time of making.
- Hold grab-and-go items in a refrigerated display or glass-door cooler, not on an open counter.
- Do not overload displays; leave room for cold air to circulate.
- Remove unsold items at the end of the day or at the time your plan sets.
- For hot sandwiches and toasted wraps, cook to order rather than holding them warm.
- Keep fillings in a refrigerated prep counter during assembly.
Avoid
- Do not display sandwiches under hot lights without refrigeration.
- Do not reuse unsold sandwiches as fillings or for staff meals the next day without a plan.
- Do not use warm fillings straight from the stove in cold sandwiches.
- Do not stack products against the display's air vents.
- Do not place fresh stock in front of older stock in the display; rotate so the oldest items sell first.
In Indian conditions
Grab-and-go food is growing quickly in Indian cities, from office canteens to railway and airport outlets. Many outlets operate in non-AC or partially open spaces where ambient temperatures are high, which pushes open-fronted displays beyond what they can hold. A glass-door refrigerator or closed refrigerated display case helps keep sandwiches within a safe range and looks professional. Paneer, chicken, egg and mayonnaise fillings are especially sensitive. Kathi rolls and frankies made to order are safer than pre-made ones held for hours. During power cuts, items in open displays warm fast; move them into a closed fridge and check temperatures before selling.
General good practice for commercial kitchens and shops. Where your FSSAI licence conditions or food-safety plan set stricter limits, follow those.
