I dislike it mainly because I find the figurative use of "vanilla" as "standard" or "generic" annoying. Vanilla is a distinct and unique flavor.
ah but in the world of ice cream and yogurt, vanilla provides the foundation or "base" as some might say for creating more flavors. So when you want to make fish flavored ice cream, you add fish to vanilla ice cream, just like adding fish to village turns it orange, gives it coins and takes away its cards...
Does fish ice cream really use vanilla ice cream as its base? I'd imagine they'd use plain ice cream or something more savory.
Also, since when does flavored yogurt begin with vanilla yogurt as a base? Maybe I'm just out of the loop since I haven't consumed animal products in many years, but that is certainly not the trend among coconut yogurt and almond yogurt.
I'm no expert on fish ice cream or yogurt, but I know that you do usually add vanilla to ice cream even if you aren't making vanilla, I believe even chocolate will have some vanilla in it, but I'm not positive. And I suppose with yogurt plain yogurt is a more common base than plain ice cream, so I apologize, that's probably wrong. and I've never had coconut yogurt or almond yogurt... sounds interesting
