The recipes should be under the "Special Recipes" section. They require tier 2 materials (6 slate blocks and 1 piece of barbed timber). So you'll either need to bump up your harvesting to 100 or buy the materials off the broker. Once you have the materials use the recipes in the Special section to complete the quest.

I completed the quest but I haven't been able to get to the amateur recipes yet. I'm on the road with work or I would check the regular recipe trainer (someone else's suggestion from another thread) but I can tell you the guy who gives you the amateur quest probably won't have any recipes for you when you finish the quest.
