Most of what gets sold as vanilla flavour has never been near a vanilla pod. It is vanillin, a single synthetic compound that mimics the dominant note of real vanilla and misses everything around it. That is fine for a cheap biscuit. It is a poor trade in anything where vanilla is meant to be the point. The trouble is the labels are written to blur the difference, so here is how to read past them.
Real vanilla is hundreds of compounds; vanillin is one
A real vanilla pod contains vanillin plus a few hundred other aromatic compounds that give it the floral, almost boozy, rounded depth you notice in good ice cream or a proper crème brûlée. Synthetic vanillin, usually made from wood pulp or petrochemicals, delivers only the central note. It is not fake in a sinister sense. It is just thin. Once you have tasted the two side by side, you cannot unhear the gap.
Decoding the labels
“Vanilla extract” or “pure vanilla extract” legally has to come from actual vanilla beans steeped in alcohol. That is what you want. “Vanilla flavouring,” “vanilla essence,” or “imitation vanilla” is usually vanillin and water with no bean involved. The words are chosen to sound similar on purpose. Reading them carefully is the same habit that pays off when you decode an olive oil label or sort out the marketing on a box of salt: the reassuring word on the front rarely matches the small print on the back.
Pods, paste, or extract
Whole pods give the best flavour and the seeds you want to see flecked through a custard, but they are expensive and fiddly. Vanilla paste is a good middle ground, thick, seedy, and easy to spoon, ideal for baking where you want both flavour and the visible specks. Pure extract is the everyday workhorse and the right default for most kitchens. Avoid anything labelled essence or flavouring if vanilla is doing real work in the recipe.
Where it is worth it and where it is not
In a heavily spiced cake, a chocolate bake, or anything where vanilla is a background player, cheap vanillin is genuinely fine and the money is better spent elsewhere. In ice cream, custard, panna cotta, plain shortbread, anything pale and simple where vanilla is the star, real extract or paste is worth every penny. Match the spend to the job. The same restraint applies to a sourdough bake versus a quick traybake: spend where the ingredient is actually tasted.
The bean shortage, briefly
Real vanilla is genuinely expensive because it is one of the most labour-intensive crops in the world, hand-pollinated and cured over months, and the supply is volatile after storms in Madagascar. That cost is why imitation exists and why the labels work so hard to look the same. Knowing why the real thing costs what it does makes the price easier to swallow when it matters.
What we keep
A bottle of pure extract for everyday baking, a jar of paste for anything where the seeds should show, and a couple of whole pods saved for the rare dish that earns them. No essence, no flavouring. Vanilla is one of those ingredients where the cheap version is not a smaller portion of the real thing. It is a different thing pretending.
