Okay, so the specks are the real star. They make your ice cream look like a starry night. You can fake it. Cheat, really. A tiny pinch of ground tonka beans gives a similar aroma plus tiny dark flecks. But tonka beans have a warning—they’re mildly toxic in huge amounts. Not for everyday use.
Or, get this: use poppy seeds. Yes, poppy seeds. They’re black, tiny, and look exactly like vanilla specks in a yellow batter. No flavor gain, but it’s a visual save. Pair it with vanilla extract, and nobody will know your secret. I won’t tell if you don’t. It’s the baking equivalent of wearing fake glasses for a photoshoot.
