How to contain the smell of truffle spice? From our trip to Venice, Italy we brought home some truffle spice. It says "truffle powder" on the small container and mainly consists of salt, flour, truffle and dried mushrooms. 

It smells delicious, but very intensive. A very small amount of powder is enough to add a nice and subtle taste to any meal. Too much could easily ruin it.

When I first opened the packaging, the smell immediately struck me. After using it for the first time, I stored it in a ziploc bag. After a day, the whole kitchen smelled like truffle as soon as I opened the spice cabinet. Since a sealable plastic bag did not seem to do the job, I took a small airtight container with the perfect size to fit it in and returned it into my cabinet.

This was some days ago, and in spite of regularly opening all windows during the day, the smell hits you when you enter the apartment. How can this spice possibly smell so intense? It is locked airtight! What else can I do?
I make tiny pouches, sousvide and then store them in a vacuum container. It works well. Takes some time to do but when you make tiny portions the rest will stay very fresh .In case you have some left in the little pouch you can put it in a small bottle with a good olive oil and use as a dressing over fried eggs or mushrooms or veg or potatoes or a deli salad...your choice. Vacuum containers are very handy since you can reuse them every time and everything stays perfect. 
I even put them in the freezer myself and the freezer does not smell at all.
