I really love eating anything that forces me to close my eyes. It's the litmus test for all the "saved bookmarks" of my palate - creating little ticklers, little flags that remind me of what to look for when perusing recipes, menus, food-zines et al. There are certain lid-dropping foods that snag me without any pause for air: sushi, chocolate, east African cuisine (yes, that's right). What is it, anyway, that can cause such rapturous delight - to the point of wanting to close one's eyes to relish in this moment, to let the moment *have you* in it's fullest capacity? I suppose we could look to science and discuss the release of endorphins and what not. But I don't find that particularly "relishing".
I just think when we allow one of our senses, in this case taste, to be completely enveloped, indulged, engaged, embraced - we are quite literally ushered into the very *moment*, via that sensory explosion - and are able to savor that tasty little moment, for just what it is. So, open your mouth and close your eyes.
