When I brought home a bottle of grapeseed oil for Foodgoat to try, he promptly opened the bottle and chugged it.
Of course the only way to try a new food item is to taste it. And grapeseed oil is a light vegetable oil (well suited to salads and, due to a high smoke point, sauteing) and not exactly freshly rendered whale blubber. It wasn't like the time my 5-year-old cousin ate an entire bottle of squeezable butter.
But I can't help it, I think any type of fat eaten straight up should be tasted, delicately, from the tip of one finger.
