How do I unlock recipes in Guild Wars 2?

I'm relatively new to Guild wars 2 as I turned to it after I felt reluctant to renew my WoW subscription. I started into leather working for my ranger class but I've only had access to the novice recipes of which I no longer gain XP from. I've tried to buy recipes from the leather working trainer that I can craft at my current level but they're all "ascended recipes" that require a much higher level. How do I get more recipes for gear I can craft at my tier?

Solution 1:

There are three ways to learn a recipe:

Automatically
Most basic component and refinement recipes are learned automatically by increasing your rank in a crafting discipline.
Discovery
Most other recipes are learned by combining ingredients from the discovery tab at a crafting station.
Recipe sheet
Some special recipes can only be unlocked by consuming a recipe sheet.

Early on, you will learn most recipes through the Discovery tab:
The discovery tab allows you to attempt to mix and match components to find a new recipe. Drag and drop or double-click items to add (or remove) them from the mix.
