You can buy this anywhere, but somehow there is always a slightly artificial flavour to it ... I made this tonight, and it's not too bad. Because Zaar's computer prefers definitive quantities, please see extra notes below. It actually needs a night in the fridge, but I didn't have the time to do that. It will not have the bright pink appearance of the supermarket taramasalata ... and I'm not going to add artificial colour!! Also, this recipe needs to be tasted, and adjusted: I bow to Zaar's computer which wants definite quantities, but the answer is still to taste and adjust. I dislike using potatoes, which gives tarama (to my taste) a rather glutinous taste.
