Lazz,
Your post caused me to go get one off one of my trees to taste. It was very good. In fact, I wonder if it might be a canidate for the quest to find a good seedless hardy citrus, with a lemon-like qualities. Do you have an idea about much cold will it take? As much as a Yuzu? I know it doesn't keep well on the tree. How about after you pick it?
