Die Antwort ist für jedes Gewürz und Mahl unterschiedlich. Die meisten Quellen, die ich gesehen habe, schlagen vor, dass 6 Monate der lange Fall für "frische Gewürze" sind, aber alle schlagen vor, in kleinen Mengen zu mahlen, damit sie nicht so lange halten.
Es folgen einige Informationen von " Spice Mogul ", einige grundlegende "Do's and Don'ts"
Machen
* Buy spices whole, versus ground, whenever possible.
* Buy in quantities that you will likely use up in 6 months time.
* Mark the date you buy your spices and dried herbs. If there are no dates on the package, take a marker and date each container when opened.
* Grind spices just before using. Grinding releases the volatile compounds that give a spice its flavor and aroma. The longer the spice sits around (either whole or ground), the more the compounds disappear and the flavors lessen.
Nicht
* Store spices and herbs on the counter or close to the stove. Remember that just like with oils, heat, light, and moisture are enemies of a spices flavor and shelf life. Cool, dry and dark should be your watch words.
* Forget to check for freshness.
* Use pre-ground spices if you can avoid it. If you must, test for flavor by rolling a small amount between your fingers and taking a whiff. If it releases a distinct aroma, you’re ok. If you have to strain to smell it, pitch it and buy fresh. There is no sense in ruining a dish full of other ingredients because your spices are not up to their full strength.
