Note: For you 'muricans who don’t get these there (presumably because the things you call Smarties are sweet candies we call Rockets here), I’m referring to Nestle’s candy-coated chocolates similar to plain M&Ms.
Now, I’ve eaten Smarties since I was a kid, though I don’t eat them often these days. Regardless of the colours, the shells always tasted the same to me and served only to be a crunchy appetizer to the chocolate within. But just now I was going through one of those treat-sized boxes, and as Og is my witness I swear the yellow ones had a barely perceptible lemon flavour – so faint I could almost chalk it up to my palate being fooled by the knowledge that it’s yellow and yellow is supposed to taste like lemon. Almost. But I could swear it’s there, faintly.
The thing is, in paying close attention to the others, it seems like yellow is the only one that appears to have any flavour at all. The rest have a nonspecific sweet taste.
Am I imagining it, or do the lemon smarties have a lemony flavour? And are the rest supposed to and I just can’t detect it?
