Updating Dinner When Two Guests Join

Two extra people at dinner change quantities even when the recipe stays the same. Updating the saved serving count is less error-prone than remembering to double only the ingredients you notice in the shop.

A two-person household plans Broccoli Tofu Rice Bowls, then two guests join.

The larger meal needs a larger shop

The planned meal requires 500 g tofu, 440 g broccoli and 280 g uncooked rice, plus the other doubled ingredients.

Update the dinner before recalculating

1. Save the rice bowls in a Dinner slot with 2 servings.
2. Change the slot to 4 servings and save again.
3. Generate shopping needs for that date with an empty inventory and no other planned meals.

The plan scales the complete recipe from two to four servings. The listed tofu, broccoli and rice examples are part of that change, not a replacement for checking the remaining ingredients.

Recalculate any unpurchased generated list after changing the serving count.
