What to use instead of tonka bean
Quick answer
The closest option is Vanilla, rated acceptable. The obvious swap, and for many readers the only legal one — tonka is prohibited as a food additive in the United States, so this is less a substitution than the available option. Vanilla occupies the same slot as the default sweet aromatic and is floral and creamy where tonka is hay-like and almond-edged. A dessert made with vanilla instead is a good dessert and a different one, and the quantities are not comparable: a whole vanilla pod against a few passes of a rasp.
It will not do for: Dishes built specifically on the hay-and-almond character; Substituting by quantity, since the two operate at completely different strengths.

Works for
- Cream and custard bases, ice creams and puddings
- Any reader in a jurisdiction where tonka is not sold as food
Does not work for
- Dishes built specifically on the hay-and-almond character
- Substituting by quantity, since the two operate at completely different strengths
Cuisine: Both are at home in European pastry, and the pair appear together as often as separately.
No ratio is given and one would be misleading: a single tonka bean flavours many dishes and a vanilla pod flavours one. Match by tasting the base rather than by measuring.
Tonka bean
PoorThe same bean, giving up the two things that make it manageable. A whole bean keeps its aroma for years because coumarin is stable and enclosed; ground, the enormous surface area loses it within months. More importantly, the whole bean can be infused and lifted out, and tonka is a spice that turns soapy and bitter when overdone with no way back — so the form that allows stopping is worth more here than almost anywhere else in this catalogue.

Works for
- Dry mixes where a bean cannot be grated in, which are rare
- Nothing else, honestly
Does not work for
- Infusions, which are the main professional use and depend on removal
- Long storage, where the whole bean is better by years rather than months
- Dosing by taste, since ground tonka commits immediately
Recorded because the question is asked, not because the swap is advisable. One bean grated to order lasts most kitchens years and costs less than a jar of the ground product.
