I have a list of items, Each item will have one of two options A or B. If the item has both options then A will always have a recipe of S (Standard) and B will always have a recipe of O (optional), However if there is ONLY the option B then B will have a recipe of S. I am a novice and can not begin to think on how to write this.

* 1\_\_\_\_A\_\_\_\_\_\_S
* 1\_\_\_\_B\_\_\_\_\_\_O
* 2\_\_\_\_B\_\_\_\_\_\_S
* 3\_\_\_\_A\_\_\_\_\_\_S
* 3\_\_\_\_B\_\_\_\_\_\_O
* 4\_\_\_\_A\_\_\_\_\_\_S
* 5\_\_\_\_A\_\_\_\_\_\_S
* 6\_\_\_\_B\_\_\_\_\_\_S
