Can I sub anise seed for fennel seed? Is it the same thing?

I tried it. It was a good substitution in this case. Thanks. I made Cioppino. There was some white wine in the broth--it would be interesting to try with Ouzo.

Not quite the same, but instead you can uses splash of ouzo or Pernod.

Not the same thing but you can usually sub one for the other, depending on what you're making. Give us some more details and we'll let you know.
