A passion is is similar to what western people call “vice.” But it has a less moral and more spiritual implications. Virtues are the opposite of passions. Patience is the opposite of anger, for example.
A preoccupation with preparing complicated (or gourmet) meals might be considered a passion of gluttony, it is up to your own conscience, to know if something is excessive or not.
Here’s a definition from an Orthodox priest:
What are passions?
Passions are the uncontrolled desires that come from our bodily needs. They subordinate our soul to our egoistic or self will. They come about because we forget about God and only think of our own needs. The seven passions are: gluttony, lust, avarice, anger, dejection, listlessness and pride. All these passions lead us to sin, but with proper discipline can be offset by virtues.
