Some restaurants, especially cafeterias and delis, use containers to hold food items. Configuring the tare weight on an item shows when that item is weighed that the weight also includes a non-food item's weight. This will subtract from the price as well.
To set the Tare Weight on a specific item, for example Tossed Garden Salad, start by clicking into the Menu section on the Toast back-end.
Search for the item and select it.
Scroll down to Advanced Properties, then down to Weighing. Select No, specify tare weight here and enter the tare weight of the container that will be holding the chosen item. In this case, the container holding the salad is 0.25.
If the item is weight embedded, this value will be subtracted from the weight of the item embedded into the barcode.
The value is relative to the unit in which the item is measured. It can be inherited from the Menu or it can be set on the Menu Group level.
