Today I went to a thai grocery store and among the refrigerated greens, there was a bunch of round little green things. Hard to describe the size exactly but imagine kinda, bigger than a blueberry but smaller than a strawberry. Kinda the size of a raspberry...I asked the shopkeeper and I am pretty certain she said something about "apples" but the rest was simply too incomprehensible for me and with the keyword "apple", I figured I would've been able to figure it out. So when I got home I took out my recently purchased book "Thai Food by David Thompson" and tried to find it but I didn't so I turned to google but with no luck there either... So, what on earth am I talking about?!
