How to Use a Vanilla Bean: Split, Scrape, Infuse

To use a vanilla bean: split it lengthways, scrape out the seeds, then infuse seeds and bean in a warm or cold preparation. Here is the technique step by step, dosage guidelines, the mistakes to avoid and how to reuse the bean.

These tips apply to any vanilla bean, including the Taha'a one, whose origin our guide tells. The techniques come from professionals listed at the bottom of the page.

Before you start: is the bean supple?

A bean in good condition is supple, glossy and fragrant, and splits without breaking. If it is dry, rehydrate it first: the method is in how to store your vanilla beans.

How do you split and scrape a vanilla bean in three steps?

Step one: lay the bean on a board and split it lengthways with the tip of a sharp knife.

Step two: open the bean and scrape the inside with the back of the blade, from one end to the other, to collect the seeds.

Step three: do not scrape too hard. Valrhona warns that you risk taking some pulp with the seeds, which leaves brown, fibrous particles. Keep the emptied bean: it will be used to infuse.

Infuse hot or cold?

Infusion is generally done in milk or cream: Valrhona explains that fat particles are what hold on to vanilla's aromas.

Hot: heat the liquid without boiling it (around 80 °C according to Galand Vanille), add the seeds and the split bean, take it off the heat, cover and leave to infuse for a few minutes. Valrhona describes woody, rounded notes, with the comfort of warm milk.

Cold: leave the split bean and seeds in milk or cream for 24 to 48 hours in the refrigerator, then strain (Galand Vanille guideline). It is the liquid, in a closed container, that goes in the refrigerator, not the bean on its own. Valrhona notes more complex and softer aromas.

Seeds only or the whole bean?

It depends on the recipe. The seeds add flavour and leave small black specks; the bean, for its part, infuses. Most often both are used together: the seeds in the preparation, the bean for the infusion, removed afterwards.

How many beans do you need?

There is no universal rule. Here are the guidelines published by a vanilla merchant, Galand Vanille. We have not tested them ourselves: adjust to your taste.

Custard, pastry cream: one bean per 50 cl of milk. Crème brûlée, panna cotta, whipped cream: one bean per 50 cl of cream.

Ice cream, sorbet: two beans per litre of base. Brioche, cake: one bean per 500 g of flour. Caramel: one bean per 250 g of sugar. Ganache: half a bean to one bean per 250 g of chocolate.

For a preparation served very cold, the same merchant suggests increasing the amount by about 50%, since cold dulls vanilla.

Which sweet recipes work with vanilla?

Custard, panna cotta, rice pudding, ice cream, financiers, cannelés: vanilla suits all the classics. If you are looking for a first recipe, try the vanilla crème brûlée with Taha'a vanilla, which puts vanilla centre stage, or the vanilla rice pudding and Bordeaux cannelés.

And vanilla in savoury dishes?

Dare to add a few seeds to white fish, scallops, poultry or a marinade. For a concrete example, see our scallops with vanilla butter. The vanilla coconut chicken and the vanilla roasted carrots show other pairings.

And in drinks?

Valrhona mentions warm milk for hot chocolate or coffee, teas, and smoothies made with a cold infusion. The principle stays the same: a split bean, some liquid, a little patience.

How do you reuse a vanilla bean?

Do not throw it away. According to Valrhona, a bean can be used at least three times: you scrape out the seeds, infuse the spent bean, then rinse it, dry it and recycle it.

Dried, it flavours a jar of sugar to make homemade vanilla sugar: Galand Vanille suggests one to two empty beans per 500 g of sugar, left for two to three weeks. Dried in the oven at 90 °C then ground, it makes a powder (Valrhona guideline).

Which mistakes should you avoid with a vanilla bean?

Boiling for a long time: Galand Vanille warns that prolonged boiling evaporates the finest aromas. Infuse off the heat, covered.

Throwing away the emptied bean: that wastes a large part of its aromatic potential. Under-dosing a cold preparation: cold dulls vanilla. Storing beans poorly: they dry out and turn brittle.

To try without committing to a large quantity, L'Unité (one bean) lets you test the method.

Should you use the whole bean or just the seeds?

Both, most of the time: the seeds in the preparation, the split bean to infuse. Depending on the recipe, you can use just one or the other.

How long should a vanilla bean infuse?

Hot, a few minutes, off the heat and covered. Cold, 24 to 48 hours in the refrigerator, in milk or cream (Galand Vanille guidelines).

Can you reuse a vanilla bean?

Yes: rinse it, dry it, then put it in sugar for vanilla sugar, or turn it into a powder once thoroughly dry.

What if the bean is dry?

Rehydrate it before use in hot milk or water. The details are in the article on storing vanilla beans.

Vanilla powder or bean: which one?

They are two different forms. The bean lets you infuse a liquid. Powder, which you can make yourself from used, dried beans, is mixed in dry. Maison Kema sells only whole beans.

How do you store a vanilla bean?

In an airtight container, away from light, at room temperature, and not in the refrigerator. Stored this way, beans keep their suppleness and fragrance for longer; over time, a bean dries out and gradually loses its aromas.
