How to request ingredients from your neighbors

 If you need ingredients for the dishes on the menu, click on the "Ingredients" tab.

There you can see how many you have left and ask them to send you more. 

It doesn't matter if you still have some or many, you can order up to 50 units of one or distribute the 50 among several.

Clicking on the pink button of one of the ingredients opens this window where your neighbors will appear.

It also tells you what you're ordering and how many you have left to order

Select the ones you want to order and they will receive a message like this

You can order up to 5 ingredients from the same person on the same day, same or different, but one at a time

You receive 10 coins for each ingredient you send, but you cannot submit any ingredients. They have to ask you.

You can't not send the ingredients they ask for. You can only accept clicking on Send button.
