For myself the best teramosalata I have found is at Village Grec (chomedey location).....bright pink, super strong and salty. The Adonis version is close, but where has anyone else found some mean teramosalata? Please don't suggest Arahova- BLASPHEMY!
You really have to make your own, if you want killer tarama. The problem with retailers is the amount of additives in the product in order that it have shelf-life.
Go to P.A. Supermarket (i.e. on du Fort) and buy a jar of cod roe. There are a zillion recipes online, but personally I find the ones that contain potato flakes to be the yummiest. Remember that it doesn't keep very long!
