Black garlic procedure

DIY Black Garlic

~~2/28/2012~~

A new batch of garlic has almost finished and I have found something very interesting. I started by buying 5# of garlic to see how large batches would turn out. I then bought two rectangle cake pans to use as my vessels, and some stacking drying racks to put the garlic on. I loaded up the two pans with the garlic, a single layer, do not stack or it could cause uneven “cooking”. I then put a piece of foil on top of the pans and then wrapped them very well with plastic to ensure that the moisture would stay in the pan. After 30 days I ended up with incredible results, the garlic was a deep black, smelled great, and didn’t have any bit of bitterness to it. Unfortunately it was only to the top pan, the pan underneath didn’t get the proper heat, so that pan went back in to cook for a little longer. But to find that the pan on top was beyond perfect is amazing to me, I removed the garlic from the pan and set it on the drying rack, which will remain there for a few days. Below are some pictures of the garlic before it has been dried and a picture of the new setup.

The pan on top was the pan on the bottom, it needs a few more days to cook. The garlic below it is drying for a few days to intensify in flavor.

The garlic needs a few days to dry to make it easier to store.

Since the day I paid $30 a pound for black garlic I was mesmerized by the process and the flavor. I wanted to know how it was done and how I could do it myself. The actual process is posted vaguely all over the internet but the creator of the name brand Black Garlic has kept his process a secret. He has built a patented “machine” to produce this garlic that has been kept quiet, at least I haven’t seen any information on it. So after reading numerous posts about making black garlic I decided to tackle this project, and since I had and old hood fan from my stove and a non-functional wine cooler, I figured I could build a warming box to re-create black garlic. Using these two items and a thermostat I was able to build a heating box where my garlic could stay nice and warm to allow fermentation. The whole heads of garlic were placed into glass mason jars, which may not be the best choice but at this point it was the best option until I understood what was going on. After a few trial runs I realized that the garlic would ferment and turn brown with little effort in about 30 days. After a full 40 days, which is the amount of time to ferment the garlic, I found that it never turned black. I removed the lids of the mason jars to see if that would help in any way, and after 15 days of that my garlic was black and hard as a rock. This rock hard garlic made me realize that I had built a very large-scale dehydration box, and that the garlic was in the open air too long. I immediately rushed to the store and bought more garlic to start the second round of fermenting. This time I had four different tests going to figure out when and how long the garlic needed to dry for. After 40 days the end results were beautiful, I had two products that were black, one that was brownish black, and one that was black and hard as a rock.

From Left Clockwise: 30 days in the mason jar and 10 days drying, (2 cloves) 5 days in the mason jar and 5 days drying, 7 days in the mason jar and 3 days out drying, 8 days in the mason jar and 2 days drying.

At the end I had three usable products out of four, which is pretty good, I used the soft and dark cloves in sauces and marinades, and the hard dried out garlic was ground up in a spice grinder to make a very pungent black garlic powder. This powder did great in rubs for pork and chicken, and did great when dehydrated in pasta dough. The color of the dough was a dull brown so I added mushroom powder to it as well to get a very nice natural looking mushroom pasta. With all of this being said, I am happy with the product and will continue to produce as much as I can. There are still a few different techniques that I want to try but until then here is the “recipe”.

What you need

  1. Warming box that can hold 140°F consistently
  2. Quart sized mason jars
  3. Garlic Bulbs
  4. Aluminum Foil
  5. 40 days of patience
  • Start by sterilizing all of your mason jars, you will need one mason jar per bulb of garlic, you do not want to stack or cram the garlic into the jars. The warm air needs to flow evenly around the bulbs of garlic.
  • Place a bulb of garlic in each mason jar and put the lid on finger tight. You do not want it too loose or the moisture from the garlic will escape.
  • Wrap each jar with aluminum foil, this will ensure that the light doesn’t affect the product and will help keep the heat even in the glass jars.
  • Place the jars in the warming box and keep the heat at 140°F for 30 days.
  • After the thirty days are up remove the foil and lids of the mason jars, there will be a little pressure built up in the jar, the garlic will be a light brown color, and should smell sweet.
  • Put the garlic back into the warming box without the lids for 10 more days, this will allow the garlic to dehydrate and concentrate the flavor.
  • At the end of the 10 days remove one clove from a bulb of garlic and make sure that it has reduced in size by more than half. If not, then continue to dehydrate for 1-2 more days.
  • Once it is black and the proper consistency remove the bulbs from their jar and let them air dry overnight on the kitchen counter. Store in the fridge or in a Ziploc bag in a cool and dark place until ready to use.

There are so many uses for this product and I have posted a few uses throughout my blog.
