The premise is simple. Make spongecake, fill with cream. The result is a creamfilled spongecake. They say Twinkies survive nuclear holocausts and the like, as shown in Wall-E and Family Guy. Sources tell me that the shelf life is actually only about 25 days. So much for heading to the nearest Twinkie factory when the bomb hits, then.
Tastewise, it's pretty clear that this product has artificial additives. Most products have that these days, but for some reason it's more apparent in a Twinkie.
I have to give Hostess credit for managing to make the Twinkie easy to eat. It can be messy, but then you're a generally messy eater.
If this product has nothing else going for it, at least it has a funny name. Especially if you pronounce it 'twawnky'.
