Apudark's guide
Fish Rolls to 135
 * No farming required. Fresh Fish and Bat Wing are both found on vendors in Plane of Knowledge. Caution: Bat Wings stack to 100 and Fresh Fish stacks to 20.

Filleted Bear to 143
 * No farming required.

Patty Melt to 191
 * No farming required.

Ohabah Truffles to 202
 * This is a really easy combine. Mushrooms can be foraged in zones like Erillion, City of Bronze, The Dead Hills, and Chapterhouse of the Fallen. Caution: Make sure you have plenty of inventory space and be aware that each combine has a large yield (cream x8, dark chocolate cream x6, and the truffles themselves x4).

From here on out, your best bet will be recipes that use Brell's Bounty, Dream Meat, Al-Metes, or Planar Goo. Collect these while you hunt and set up a buyer in The Bazaar during your downtime. All of these can be used to get to 300 and max your trophy.

Smoked Brell's Bounty Stew to 250

Bucket of Crab Legs to 288
 * Regrua Claws drop in large quantities in Plane of Water. Each claw you farm will yield two combines. Farm Hraquis at the same time for parts for tribute bows.

Anything mentioned above to 300

Broiled Raxil Fish to 415 (trivial)
 * Fish for Raxil Fish in Argath, Bastion of Ildaera and max out your fishing at the same time. Make sure to buy the forage AA so you can also forage Al-Metes and Essence of Alaris while you fish.

Cookies to 102

Cookies:
 * Clump of Dough
 * Frosting
 * Spices

Notes: Cookies yay!

Clump of Dough can be made many WAYS, but the easiest is combining a Bottle of Milk, Cup of Flour (both can be bough from Culkin Ironstove of the eastern trade building, PoK), and Basilisk Egg, most easily farmed in Lavastorm Mountains, outside of the Wayfarer's camp, but there are other ZONES were basilisks can be found.

Frosting and Spices can also be found on good old Culkin Ironstove. What a nice man.

Smoked Brell's Bounty Stew to 250

Smoked Brell's Bounty Stew:
 * Pot
 * Smoked Brell's Bounty
 * Vegetables
 * Water Flask

Notes: Pot (You'll only need one) can be easily made by yourself or some potter you may find. If your a DIY kind of tradeskiller, click HERE for more information.

Smoked Brell's Bounty needs four subcombines.
 * First make Prepared Brell's Bounty by combining Brell's Bounty and a Water Flask (trivial 68).
 * Second make some Smoking Sauce by combining Garlic, Spices, Vinegar (all found on Cook Kosey of Crescent Reach), with Vegetable Oil. (Brewing trivial of 62)
 * Thirdly, Vegetable Oil is made by combining Vegetable and Water Flask (Brewing trivial of 102).
 * Fourthly, Vegetables can be made by combining Carrot, Lettuce and Turnip (all bought from Merchant Oseye of Crescent Reach) (No-Fail trivial of 15 in a mixing bowl).

Combine the Prepared Brell's Bounty with the Smoking Sauce in a mixing bowl (trivial 139) to make the Smoked Brell's Bounty.

Grilled Stuffed Brell's Bounty to 402

Grilled Stuffed Brell's Bounty:
 * Cheese
 * Ground Pepper
 * Hot Red Pepper
 * Onion
 * Prepared Brells's Bounty
 * Vinegar

Notes: Cheese can be found on Merchant Oseye of Crescent Reach. Ground Pepper, Hot Red pepper, Onion and, Vinegar can all be found on Cook Kosey, also of Crescent Reach. You should know how to make Prepared Brell's Bounty at this point.

If you think this is far too time/farm intensive, I implore you to give up Baking. All other combines are just as terrifying, in one way or the other. If you know better, please post a recipe or link.
