An Empty Tracker After Cooking Dinner

A new tracker should stay empty after food is used for its intended dinner. This is an important boundary: reduced inventory alone is not evidence of a wasted ingredient.

A new local data profile has one 500 g carrot batch and no discard records.

The recorded use leaves three hundred twenty grams in stock. No loss was confirmed, so there is no reason to manufacture a waste event for the one hundred eighty grams that went into the meal.

Cook from the carrot batch

1. Record 180 g as Used in cooking.
2. Open Food Waste Tracker and review the current month.
3. Return to inventory.

The tracker still has no discard

The tracker has no discard events and the batch contains 320 g.

Only confirm a discard for an amount actually thrown away.
