I have found it difficult to find good quality Vanilla on the street because it can be preserved with oil and then smells
rancid. I have bought just a small bundle from time to time from outdoor markets for 15,000ar ( 75,000FMG)

I read an article some 6 years ago that to increase the weight of the vanilla pods they would insert metal pins.

Here is the Article in English
Vanilla production is estimated at around 1,800 tonnes this year and good production quality promotes industry

Madagascar remains still the world champion of vanilla in both quantity and quality. A status which will once again be confirmed with a forecast of good quality this year. "Producers process, mostly to harvest mature vanilla beans," says a professional who is looking forward to the good performance the sale of semi-prepared vanilla . "Even the preparation follows the standards because many preparers proceed drying in the sun," continues our interlocutor. However, some preparers still dare use the vacuum of their production. So everyone is a winner of this good quality vanilla. Starting with the producers themselves who can sell a kilo of vanilla semi prepared at prices ranging between 50,000 and 75,000 MGA MGA according to quality.

More than $ 75 a kilo. Exporters also welcome this good quality vanilla insofar as it will allow them to charge a reasonable price in the international market. A price that could easily exceed $ 75 per kilo. This will obviously be a good option for the entire industry. Especially when we know that the amount of vanilla exported will also increase. "vanilla production could be exported until 1800 tons go this year," A year Madagascar provide not less than 90% of the vanilla in the world market. Indeed, apart from Uganda trying somehow to keep pace, the other producing countries like India, Indonesia, Papua New Guinea are still virtually inactive in the vanilla market.

It was my impression you can buy vanilla throughout Madagascar. In August, at Ranomafana, I bought two vacuum-sealed packs of pods, each weighing about 40g and containing 12 pods, for 15,000ar (about £3.50 or a little under $5). These are soft, cured pods, and very perfumed. The typical supermarket price of dried pods in the UK is £2 a pod.

I too got more curious about vanilla and found this
