Online (like if someone posts a good recipe here, I might try it out)
Sometimes I just have an idea and check if anyone has done it (google) and try to mix different techniques, still make it my own, in a way.
Other times, I'm just reading a magazine and they have a recipe section. If I like it, I tear off the page. :hah: Lastly, I bought cookbooks before and were offered too. I still haven't tried all recipes there.
