Basics:
Delicious: Emily's Childhood Memories is one of the "Delicious" series of time management game. A customer's order will appear in a thought balloon over his head, and you play (mostly) as Emily, serving the customer by preparing the food. For most items, this simply requires clicking on the corresponding food; other food may require several steps. This game contains an excellent basic tutorial before the first level; if you've not played one of the Delicious games before, I recommend you play it.
Tip: This game can be slow to load levels. Don't panic, thinking that it's frozen; just give it a little more time than you would usually allow.
