What are adzuki beans?
Adzuki beans are tiny little shiny red legumes about 5mm long. They come from an ancient vine widely cultivated throughout East Asia. There are other varieties in colours mottled, grey, white and black.
Also known as azuki bean, aduki bean, red bean, or red mung bean, their Latin name is Vigna Angularis.
They are commonly used in Japanese and Chinese desserts, cooking them with sugar or turning them into a paste to use in prized recipes. In Japan, they're also used to make the fermented dish Natto.
Once they've been sprouted, I love to add them raw to salads and bowls. However, they can also be added to chillies, curries, soups and stews.
What you'll need
For sprouting adzuki beans in a jar, you'll need some dried adzuki beans, a wide-mouthed mason jar, and fresh, cold water.
If you don't have a suitably sized sprouting lid, use a piece of cheesecloth with a rubber band to hold the cloth over the top of the jar. This will prevent the beans from spilling out and also help keep them clean while sprouting.
I like to use organic adzuki beans grown specifically for sprouting as I have the most success with these. Be sure to use dried adzuki beans, not the tinned versions, which will have been cooked.
You can search specifically for them among sprouting seeds companies online. Certified sprouting seeds that are sold in the UK are required to have been through thorough testing before being sold as such.
Instructions
The steps for growing adzuki bean sprouts are as follows:
Step 1 - Rinse the beans well, picking out any pieces of grit or broken beans before adding them to a mason jar or bowl. Cover the beans with 3 times the amount of water, as they will soak up a good amount. Expect them to double or triple in size overall.
Step 2 - Soak adzuki beans for 8-12 hours. I like to leave them overnight as I get more sprouts with a longer soaking time (I do 12 hours). Now, drain the soak water from the beans using a strainer and rinse them well. Be sure to drain them for a few minutes so they don't sit in any residual water.
Step 3 -Leave the beans to sprout in a jar for 3-5 days. Repeat rinsing/draining twice daily during this time, until the beans have sprouted.
For exact quantities, see the recipe below.
TIP: Place the mason jar upturned about 90 degrees into a bowl. This helps to ensure any excess water drains off after rinsing.
I like to leave them on the countertop to one side so I can keep an eye on them. It takes a full 5 days in cooler weather before I see my adzuki beans sprouting at home. So, try not to be disheartened if they don't shoot up as quickly as other sprouts.
Please give them a final rinse when they're ready. I like them when the tail's about the same length as the bean or more. Although, some people prefer them when their tail is longer - about 2cm long. It's really down to your own personal preference.
Also, their little outer jacket will split during the sprouting process, revealing the light cream-coloured bean underneath. Again, some people like to remove any loose outer layers which sometimes separate from the bean.
I enjoy them as is.
Storing
Store your adzuki bean sprouts in a container in the fridge for up to 3 days. Use a lidded container and line it with a paper towel to draw up any excess water after rinsing and draining.

- Step 3 - Sprout adzuki beans in the mason jar over the next 3-5 days, remembering to rinse and drain them twice daily. Morning and evening are good times to do this.
- Finally - When ready and their tails have grown as long as the bean or a little more, give them a rinse and drain them before use. You can now store adzuki bean sprouts in the refrigerator for up to 3 days in a lidded container on kitchen paper. Please rinse and drain each day to help them stay fresh!
Notes
Food safety
The UK Food Standards Agency recommends people in vulnerable groups always cook any sprouts until steaming hot all the way through before eating them.
This is because sprouts sometimes contain bacteria, which some people may be susceptible to. Vulnerable groups include the elderly, young children, those with a weakened immune system, and pregnant women.
Never eat sprouts or microgreens that look or smell bad or weird. If you're unsure, then throw them out and start again.
Not all seeds or beans are suitable for sprouting or eating raw. Please be sure to check first.
Check the FSA website for more details.
