I'm probably going to sound like all I do is eat by posting yet again about food, but it's just that I'm hungry at the moment. :P
Whether in America or in Japan, one thing I absolutely love to have as a snack is a warm cup of black tea with a little milk with some sort of baked good on the side. And while I was in Japan, thankfully I didn't have to settle for boring old cookies!
Pudding parfaits! Whenever I went to the store, I always checked for these (they tended to sell out of them a lot! Although I did tend to go to the store later in the day). This one was kind of a mix of a layer of pudding, a layer of cake, and strawberries in syrup, topped with whipped cream, a bit of cheesecake, and a little chocolate straw.
I haven't been able to find something exactly like this where I live, although I do live in the middle of nowhere. If I do see something similar at the store, they're much larger (maybe twice the size as this one). Maybe I should try making my own...
