Going further?

Throwing some ideas I have since a while on this subject.

Once you have a recipe, I find it hard to produce a list of all ingredients you have to buy, and then pick them individually. Indeed, you may have leftovers, and you need to calculate quantities depending on the number of people. This is also dependent on the store and the food producer you use. Then my next question is: what else/related dish could I make with the rest - even if I may need a few more ingredients? I always wanted a helper like this. And eventually, send this list to an online grocery. La crème de la crème!
