We generally do something like this:
-A slosh of apple cider (use the good unfiltered kind, it’ll make a difference)
-A big old blob of plain yogurt
-A banana or two
-Other fruit, fresh or frozen
It’s a great start to the day.
I also do fake lassis in the summertime, using full-fat buttermilk; my guess is you could do something similar with yogurt.
-A blob of yogurt
-A slob of honey
-Fresh cardamom if you want
-Mango or peaches
-Maybe some juice or nectar to thin it out
I’m not sure it loses its flavor. If anything, I would expect it to get stronger with time.
For me, I use yogurt a lot with curries and things like that. Great for marinating meat in with spices–that sort of thing. Also, anywhere sour cream or buttermilk goes well, you can sub yogurt for the same idea, but slightly different flavor.
x2 The trick is to properly dry the cucumber so your tzatziki isn’t watery. Why tzatziki isn’t bigger than French fries is a mystery to me. Hell, why French fries dipped in tzatziki isn’t bigger than ketchup is a mystery to me.
Don’t worry about it losing its flavor. I’m assuming you live alone? If you’re concerned about spoilage, you can freeze it although the texture will change when it thaws.
What you want to do is slice the cucumber longitudinally, spoon out all the watery middle and seeds and discard, grate the rest and leave out in the hot Aegean sun until you have dry cucumber flakes like the onions in dry onion soup mix. The recipe talks about drawing (some) water from the cucumber. I’m talking about drying cucumber so that it draws water out of the yogurt.
Too sweet and tasteless, use real cucumbers, garden fresh if possible. Same goes for American “Greek” yogurt which isn’t even strained but just uses thickeners (and probably adds sugar.) Straining thickens, but also leaches out some of the lactose.
