Tell it when you want to sit down to eat. It builds the cooking plan backwards from there and warns you where your oven is about to let you down.
Tick only what you actually own. The timeline suggests moving dishes off the oven, and it will never suggest equipment you don't have.
Add everyone you've invited. Dietary needs are checked against your menu, and you can note who is bringing what.
Rough starting amounts based on the guests who said yes. Appetites vary, so treat these as a floor rather than a rule.
Enter what you own and see the gap before the day, not an hour before.
Every ingredient from your dishes, merged and sorted by where you'll find it in the shop. Add ingredients to a dish on the Menu tab.
The two weeks leading up to the day. Add your own jobs, set how many days before they happen, and move them into place.
Pick what goes on paper. Everything else stays on screen.
In the print dialog, choose "Save as PDF" if you'd rather keep it on your phone than on the fridge.
Your plan saves itself on this device as you type. A backup file lets you move it to another device or keep it for next year.
