7-10 levels offering such lovely skills as:
(Existing Skills)
Cooking
Carving
Herbalism
Knowledge of Ingredients
Knowledge of Mushrooms
Mixing
Plant Lore
(New Skills)
Baking (create cakes, cookies, brownies, pies, etc. Recovers HP. Skill use for exp?)
Bottling (create various juices using berries/plants. Recovers SP. Skill use for exp?)
Brewing (Create various wines[cooking or drinking]/ales/drinks, etc. Various Stat affects, dependant on the brew, i.e. increased str + reduced int. Increased cha + reduced dex. etc, etc. Skill use for exp?)
Gourmet Selection (allows the chef a chance to find better ingredients. i.e. skinning would have a chance to yield more than just "chunk of meat"... something like a "flank steak of [animal name]" or "[animal name] roast", etc, etc. Likewise, the herbalism skill could have a chance to yield additional items like wheat from plains, onions from meadows, rice from river banks, whatever)
Prepare Ingredients (Used like mixing, but to prepare specific cooking ingredients. i.e. "Use Prepare Ingredients at starflour" would turn starflowers into starflour

Preserves (Make foods easy to store, so they remain after logout)
Master Cookware (use of specialty equipment dramatically reduces cooking time)
Mastery of Seasonings (Increases HP/EP recovery from eating foods prepared by a Master Chef)
Mastery of Cooking Styles (Increases the number of random "Dishes" that can be created using the Cooking Skill)
**********************
While they'll have a whole array of skills to use, and many delicious items to make, the traditional Cooking skill is still going to be their focus. However, with increased "Mastery of Cooking Styles" they'll no longer just turn out "Cooked chunk of [animal] meat"... instead, they'll randomly produce "[adjective] [animal] sandwich" or "[adjective] [animal] stew"... As their skill goes up, different adjectives will describe the quality of the item created (bitter, salty, average, good, fine, tastey, delicious, excellent, FAN-FREAKING-TASTIC). The foods produced by an accomplished Chef will also provide healing/recovery in addition to fulfilling the basic eating requirements for the lucky diner.

Well... it was just brought up the other day on the Alchemist channel... Belannaer mentioned something about intending to impliment a cooking guild... so... I'm really kinda hungry, and bored, and crazy... This is the result.
