I was amazed at how good this is for canned fruit (which I normally won't touch).  In particular I adore papayas and mangos.  The fruit juice instead of syrup is also very nice.  The easy pull-top on the can makes this a great item to stash in my desk drawer at work, so that I can have a fruit snack easily even if I was too busy or forgot to bring lunch.  So far I haven't gotten a can that had any problems.  The watermelon isn't crunchy - of course not! - but it's good, and certainly not "slimy".

My first time having Curry Rice.  But boy, I cooked this stuff exactly how you're supposed to.  Taste...wasn't bad, I guess, a little "Strong" though.  IT was thick, like ice slush...it was over-bearing and the spice was pretty intense.  I don't think I'll get it again...I guess it's good stuff, seen it in some curry making videos...used often, but...not for me, as it it is way to thick.  I had potatoes, onions, and pork prepared to perfection mixed with it...and I could not taste them, at all. I could not taste the pork, or anything. Only the Sauce.

I was given a track number and told it was delivered to my POBOX.  It never happened.  I received a refund and am now in the process of wating for my new reorder.
