When they are ripe, especially the red skin/red flesh ones or the yellow skin ones, are really good. Problem is most of them sold in the US are very mediocre and tasteless. (Tbh that’s true for most fruits, peaches or melons or most fruit I find here are in the supermarket are terribly bland).
I get the better tasting ripe ones in Asian grocers or in Chinatown, I usually follow and ask Asian aunties and grandmas, they know where the best stuff is. But red skin/white flesh is usually disappointing unless you are really lucky, so try the others.
The above is/was correct, but for the last 1-2 years they actually flipped it around, artificially valuing the currency against USD, EUR while not keeping inflation under check. The inflation in TRY has been >100% for the last few years, while the TRY/USD parity barely moved. So it means that the prices are approximately at NYC levels for e.g. restaurants, and is shockingly expensive for most tourists, let alone the local people.
