Tyri = cheese, Kafteri = hot, as in spicy. So there you have it, a spicy feta cheese dip or spread. Goes great on an appetizer tray and makes anything dipped in it taste fantastic. A word of caution though - don't use the dried-up feta from the grocery store. Please use a good quality feta from an ethnic deli, or at least a mass produced feta that comes packaged in brine (TJ's or WF are good options). I found this recipe on Elly Says Opa - and believe me, you'll be saying "opa", too!
