Greek yogurt does taste different, and it's really good. I can only find it here at the Fresh Market. Too expensive, in my opinion, for what I'm willing to spend for yogurt.
Several years ago, I went to Greece with 3 women friends, and had it there. Over there it's served plain, with honey or fresh fruit to add in to one's specific tastes. It's incredible with fresh peaches, blueberries or raspberries.
Two of the women also added honey with the fruit, but I thought it made it too sweet.
Even so, I'm not going to add it, or any other yogurt, to potato salad, cole slaw or put it on baked potatoes. Yuk.
Dannon and Kroger-brand, both have a "vanilla" yogurt that is similar, and I will either add cinnamon sugar to it, or fresh fruit. If I'm adding stuff to it, the Kroger brand is just as good at almost half the price.
To me, sour cream and yogurt are not interchangeable.
Well now, when I was wandering through the socialist paradises of the workers and peasants with free medical care for all during the 1990s, I had ample opportunity to dine on yogurt, and it seems the Russian, Ukrainian, White Russian, and Moldavian peasants presented it the same way you found it in Greece.
I always took it with peaches.
Sour cream and yogurt are two entirely different things, but damn, both are good.
By the way, a question that might, or might not, stray from this thread.
This has been a bumper year for crops out here in the Sandhills of Nebraska, and I've been inundated with cucumbers. Bushel-baskets of cucumbers.
I like cucumbers; ever since I was a little kid, I've just yanked them off the vine and dined upon them as if popsicles.
But damn, there's just so many cucumbers.
Since during hot weather, I like to jam fresh vegetables or fruits into a blender with ice, liquifying them, I decided I would make some juice out of these cucumbers.
It worked, but I'm getting only about two-thirds a pint of water (juice) per two large cucumbers.
(That's after it's been strained.)
Surely there's more water in them than that; perhaps I'm not having the blender run long enough?
I have a state-of-the-art industrial strength blender (glass container, not cheap plastic), but usually I run it for no more than thirty seconds before shutting it off. Blenders explode.
