The challenges for home cook in preparing a more involving dish is lacking in the economy of scale in which a specialized restaurant has. For someone's most cooking is for a party of one the challenges multiplies. Over the years I adapted and developed methods to alleviate them. For example, when making stock I make a very big batch but leaving the soup base open to a wide variety of possible end dishes. I also learnt that to prolong the shelf life of the stock by re-boiling it after a few days.
