Allhabad RED is not the Safeda variety which is what Ashok has. I think the red is called Allahabad Surkha. Have been trying to get this one for sometimes now with no luck at all.
I asked because I saw the ALLAHABAD RED on EBAY. The seller has a big price on them but it looks as if they are very negotiable. I have several common varieties here (mexican cream, Thai white, lemon, strawberry, pink) and truthfully I must not have a discriminating palette because I love all those that fruited so far.
Maybe Rob can weigh in here on some unusual and flavorful locally available guavas?
