So where do you buy fish eggs at? Do you just go ask at the seafood counter for some fish eggs? I bought some type of little fish that looked like/was sardines and they had eggs in them but I cooked it so I couldn't really taste it. We usually buy our fish/seafood at an Asian grocery store or grocery stores catered to our ethinicity. Do you eat the roe raw or cooked? Is it safe to eat roe from these places raw? What are the benefits of eating it and how much should you eat to get those benefits?
Believe it or not, I buy fish roe at Ikea - yes, the giant furniture store. Ikea sells Swedish food. My mom is from Sweden and I grew up eating some weird stuff, including fish roe. This kind would be frowned upon by most paleo folk because it contains small amounts of sugar and canola oil, but I figure I'm eating only a teaspoonful at a time so I let it slide. There's not enough sugar in it to make it taste sweet at all. It comes in a toothpaste-sized tube for about $3, and it makes hard-boiled eggs into little balls of heaven.
I highly recommend finding a Japanese or Russian store. I get a Wild caught salmon roe at my Russian store called "Peter Pan" for about 25 dollars a pound which compared to Whole food's 16 bucks an ounce is a good deal.
If I lived on the west coast, I would buy from here. I'm not positive that it's human-grade, since it's supposed to be bait, but it looks like it could be.
Oh, and something to keep in mind: I think sushi roe and most caviar is processed (cured, marinated in something like soy sauce or other sauce) that makes it not completely gluten free. It's something to look into if you're sensitive to trace amounts of gluten.
