There are a lot of things you can do for baking, Dream Meat, Al-metes, Planar Goo, Brell's Bounties (ground spawn in Underfoot, locks listed on Allah). I'm sure I'm missing a few also.
EQTC - Item: Grilled Stuffed Brell's Bounty - is what I used on brell's bounties - 402 trivial and there is only 1 sub combine (prepping the bounty which basically you have to do on any high end baking skill)
I would have to look at what I made when I get home for the rest, don't recall of the top of my head, I just went down the quick trivial list and went new the end then looked for the ones with least sub combines to do. Was rather easy one to 300 with so many options of items to use that can be gotten in bazaar easily and I also just sat my rogue around in Brell's Rest and CC collecting brell's bounties well I was working on other trade skills, so got a lot of combines without having to buy items or farm.
