Greetings from the UK. I have a problem for which I need advice on the best way to solve it.

I have a smoothie recipe book that I want to work out the most efficient way to buy the ingredients. I thought of using a Venn diagram to show me what ingredients are used in many recipes with the few extra I need to add. I have found software to do this, but there would be too many sets, so I wonder whether there is a better way to do it.

I work in IT, so could use software or write code to do it, but I need to know the best way to approach it.

Any help would be appreciated.

Regards,

Chris
