Little frustrating as a brand new player and cook that I can't pick up this stuff without getting involved in player auctions or whatever that's called in this game. You even get a quest at level 10-ish to make Roast Pork, but you need Yellow Onion to make the Roast Pork, and you cannot get the Yellow Onion from any vendor.
Perhaps one could alter the crafting quests to only require ingredients purchasable. I should forward that suggestion to Turbine. Level 16 now and I haven't skilled up once in Cooking, because I have to comb the map for every single vendor just to make some biscuits that are already too low level for me to benefit from.
Sigh.
