Recalculating the Same Meal List

A second calculation is often a check, not a request for another breakfast. Rebuilding the unpurchased requirement should therefore show what the meal needs now, without adding the first result to itself.

A list covers one two-serving scramble and no inventory is recorded.

Calculate the unchanged meal twice

1. Calculate the list for the chosen meal date.
2. Note the 4 each egg line.
3. Calculate again for the same range without changing plans or stock.

The egg shortage stays the same

The refreshed unpurchased list still needs 4 eggs, not 8.

The generated lines are refreshed from the plan and stock. Repeating that calculation does not mean the household intends to cook the same saved slot twice.

Keep manual extra purchases separate from calculated recipe requirements.
