Can I freeze tzatziki sauce?
I tried freezing tzatziki sauce but wasn't happy with it when thawed as it seemed to separate easily and even when mixed thoroughly it seemed to have a different, more watery texture than when fresh.

What I do now if I have cucumbers I need to use is to prepare and process them exactly as I would for fresh tzatziki sauce. I freeze the processed cucumber in 1/2 or 1 cup containers and thaw to make fresh tzatziki sauce. Works great and the added bonus is that it doesn't take up as much room in the freezer.
