Check list

If you are cooking get recipes all together and write a detailed grocery list.

Some web sites will allow you to calculate the amount of items you will need to make a recipe for x amount of guest, by just adding the number of people you are serving. But remember not every one will take the same amount and if you are serving 3 salads for example you will need less.
