The process of making black garlic is less difficult than it is long. It can be aged for up to 60 days, but will be ready to use after three weeks. There are quite a few DIY methods.
If you plan on making black garlic frequently, purchasing a fermenting box can be a great investment. However, the best approach without additional kitchenware is to age your bulbs in a slow cooker or rice cooker.
The process is easy but takes patience to achieve that super sweet result. As an additional warning, you will have that strong garlic smell wafting in your kitchen for the entire cooking process. When planning where to place the cooker, think about the best spot to minimize the odor.
As it cooks and turns black, the garlic gets rock hard and seems like a failure. Remove any dirt from the garlic bulbs by scrubbing the bulbs gently with the rough side of a clean, unused sponge. Do not remove the cloves from the bulb and do not wash or wet the bulbs as this will disrupt the aging process.
Set your slow cooker or rice cooker to warm not low. The warm setting provides just the right temperature and humidity for aging without cooking. Place whole, unpeeled, scrubbed garlic bulbs into the cooker. Do not overcrowd the bulbs. Leave enough space between the bulbs so they that do not touch. Allow the bulbs to sit uninterrupted on the "warm" setting until the cloves are soft and black 2 to 3 weeks.
Check the slow cooker occasionally to make sure the setting is still on "warm" not "low" and that it hasn't switched off.
When ready, store the bulbs whole in an airtight container for up to 3 months. There are no bacteria or micro-organisms involved in making black garlic. It is actually produced by a form of slow cooking: a low, slow roast that involves a gradual breakdown of sugars over time.
It is partly the heat denaturing the enzyme allinase and partly a Maillard reaction that causes a stream of chemical changes, producing dark brown and black clove colours, and the complex, sulphurous caramelised flavour. The Maillard reaction is a chemical reaction between an amino acid and a reducing sugar, usually requiring heat, and is a form of non-enzymatic browning Block, E.
It can be done in an electric rice cooker, slow cooker or electric dehydrator as long as you can seal in moisture or equivalent. Select good-quality garlic bulbs no mouldy or damaged cloves , remove any loose skin but leave the bulb wrappers intact and moisten the outside of each bulb with water.
Wrap 6 or 7 bulbs together in two layers of aluminium foil so they are well sealed. Repeat if you have more bulbs. Sit the wrapped bulbs in a container so they are not actually touching the bottom of the bowl. You can find aged black garlic and fermented black garlic sold as whole bulbs, peeled cloves, as a puree, or dried and granulated.
If you want to use black garlic in recipes as you would regular raw or roasted garlic, look for bulbs, cloves, or purees. To purchase black garlic in bulk, your best option is an online retailer. And while you can make black garlic at home by placing full bulbs in a slow cooker or rice cooker on the low setting, it will take two to six weeks for the garlic to fully mature.
Whole bulbs of unpeeled black garlic can be stored in their packaging at room temperature until opened. Once opened the package should be stored in the refrigerator until the best-by or use-by date. Black garlic will usually last up to one month in the refrigerator. Peeled whole or diced black garlic cloves and purees should be stored in airtight containers or glass jars in the refrigerator and used by the date indicated on the packaging. Just like fresh garlic, black garlic can be eaten raw or cooked.
If you purchase whole bulbs of black garlic you will need to peel the cloves before using, but this takes much less time than peeling fresh garlic.
The cloves should easily pull away from the skins. Once peeled black garlic can be sliced, minced, or mashed and added to any recipe that uses fresh garlic. Keep in mind, however, that black garlic does not have the pungent flavor of fresh garlic, so its flavor can be overwhelmed by other ingredients. You may need to use more black garlic than you would fresh or use it in recipes with simple flavors to let its uniqueness really stand out. Here are a few ways to use black garlic:.
Black garlic can be used in any recipe where garlic is an ingredient. It is delicious. Does this mean the proofer would be out of commission for any other use during the weeks? Or can the pot be removed and placed in an oven or on low on the stove top? Jeanne Great question. It is probably fine to remove the garlic container from the proofer for a few hours and keep it in a warm place.
We would suggest that letting it get a bit cooler for a few hours would be better than overheating it. Be careful using the oven. Low temperature control in a conventional oven is typically very poor. I have produced Black Garlic using a yoghurt maker set to 41 degrees that I use for making probiotoc yoghurt with thermophilic cultures The yoghurt takes between hours depending on the tangyness I am after, which I vary slightly between the thickened yoghurts i have made, the labna style yoghurt cheeses, the drinking yoghurts and plain yoghurts.
The black garlic took six weeks, i see no reason to believe that it that this temperature and with high humidity, fermentation with wild yeasts would not have occured I have also made black garlic in a slow cooker, using a wet bed of straw at the base and sides to stop direct contact with heated surfaces, and foil wrap to stabilise moisture.
The temperature here was around 60 degrees which is obviously specifically chosen to be high enough enough to kill off most bacteria and yeast, so in this case I see your point.
I first encountered Black Garlic back in the 80s when friends made it in a earthen crock buried in a hot compost heap. This is how I understand it was done traditionally. Dave Thanks for your comments and link to an interesting article. We are not biochemists, but from our readings still understand that the technique we recommend for making black garlic at 60C does not involve any bacterial or yeast processes.
It is a thermal Maillard reaction. A careful reading of the article you mention, and several of the references, reveals several points. While they use this term repeatedly in the introductory paragraphs, they then describe a thermal process involving the Maillard reaction. Perhaps this is a language issue. One of the references: The Comparison of the Contents of Sugar, Amadori, and Heyns Compounds in Fresh and Black Garlic, also describes an analysis of the Maillard reaction with regard to sugars in the black garlic.
The 60C process that we recommend, and seems to be used widely be others making black garlic at home or professionally, is to our understanding, completely thermal and not biological. Just wanted to stop by and say that. Keep on keeping on. I grow my own hard-neck garlic, put 10 bulbs in a simple rice cooker for 3 weeks, turned lovely black, soft, deep taste.
We then made the black garlic orange sauce recipe and glazed baked salmon. Still have some of the taste in our mouths an hour later. We find totally conflicting recommendations on storage of black garlic from do not peel and refrigerate to peel all and put in paper bag inside hermetically sealed plastic bag.
Thomas, Thank you for contacting us. We are delighted you were pleased with the recipe. It is a customer favorite. After about 12 hours we divide the pieces into a quantities suitable for recipes, place each group in a vacuum-seal bag and vacuum seal them before freezing.
We have had frozen black garlic for 6 months this way with great success. We do not have another tried and tested method to recommend at this time but if we do in the future we will be certain to post the results. Just tried my first cloves of black garlic.
