How To Convert Fresh Herb to Dried Herbs
Let me start by saying I try to use fresh herbs over dried herbs as much as humanly possible. We grow fresh herbs in the spring and summer; many last through the fall and some right into winter.
If we don't have them in the backyard, they are easy enough to find at the supermarket. Still, they can get costly at certain times of the year so if you only need a little of a particular herb for a recipe, be sure to incorporate it into something else you are preparing. If all else fails, make a soup or stew and use up some of those herbs.
How Fresh Are Your Dried Herbs?
I wouldn't say I like using dried herbs because I never know how long they've been in the spice cabinet. Generally, ground spices and herb leaves will be considered "fresh" if stored in optimal conditions for 1 to 2 years.
I know some of the spice jars in my pantry are as old as my kids, well, maybe not that old, but they do tend to get lost and unused, especially those in the back.
And what about when you purchase a new container but feel like you have to wait until you finish the older jar, even if the spices in it are flavorless? I suppose we should all use a permanent marker and date the jars as soon as we purchase them or put a throw-out date on them but then how do we know how long they've been in some storage facility or supermarket shelves?
How do we really know how much shelf life is left in our seasonings?
I don't think we do, so I suggest that before you start cooking a meal that requires dried herbs, you check your spice cabinet to ensure you have what you need and then give them a quick sniff and taste to make sure they are fresh enough to use.
If they don't taste as potent as you like, you may need to add more than called to make up for the difference.
All You Really Need To Know About Converting Fresh Herbs to Dry Herbs
The general rule for dried "flaky" herbs like dried cilantro or dried tarragon is 3 to 1 or three parts fresh to one part dried. You can also look at this as
1 tablespoon fresh herbs = 1 teaspoon dried herbs
If you are working with dried ground herbs like ground ginger, which will be even more potent than the dried flaky herbs, the general ratio is 4 to 1 or four parts fresh to one part dried.
Another general rule:
1 teaspoon dried leaf herb = ½ teaspoon ground dried herb
Why These Ratios?
If you're wondering why you need so many more fresh herbs than dried herbs, you must remember that fresh herbs like basil and parsley are 80% to 90% water. In the drying process, the water evaporates, leaving highly potent essential oils with more concentrated flavors than their fresh counterparts.
When you talk about rosemary and thyme with even harder leaves than basil, flavor intensity can be even more significant, so be careful when adding these dried spices to a dish.
Exceptions to the Rule
Like everything in life, there are always exceptions to my general rules above. For example, you would substitute one fresh bay leaf for two dried or one medium onion for one teaspoon of onion powder. Both basil and parsley surprised me with a 2 to 1 fresh to dried.
I searched the Internet to see what I could find for these conversions and came up with this chart. There was no consensus between all the sites, but this should be a good start to work with until you come up with your ratios.
Print & Save
There's no way I will remember all these conversions, so I'll make a copy of the chart below and print it out, then tape it to the inside of one of my cabinet doors, so it's handy when I need it. It sits right next to my Meat Doneness Chart.
