Growing shorter sprouts for South Asian recipes

  • Put the soaked, rinsed and drained mung beans back in the same bowl.
  • Cover and place in a warm spot for 18-24 hours.
    Check notes to grow sprouts in winter.
  • Rinse and use in recipes like this sprouts salad. Refrigerate if not using immediately.

Growing longer sprouts for Southeast Asian recipes

  • Add soaked rinsed & drained mung beans into a colander lined with paper towel/muslin cloth.
  • Place the colander in a larger bowl, so that water can drip out. It will also help in keeping the light out, so choose an opaque bowl.
    Note: I use this two tier steamer as my sprouting apparatus.
    steamer to grow mung bean sprouts
  • Place a plate on top of the beans. This makes the shoots grow thick and strong.
  • Cover with a dark coloured towel so that light cannot enter into the colander.
  • Now, place the entire setup in a warm, dark spot where light cannot enter.
  • Twice every day(morning & evening), take the colander out, remove the towel and the plate and give the sprouts a good rinse under running water as it requires moisture to grow healthy.
  • Every time you rinse, remember to discard the water that has collected in the drainage bowl.
  • Place the colander back in the bowl, place the heavy plate on top and cover with the dark colored towel.
  • Repeat steps 6-8 twice everyday for 3-5 days or until the bean sprouts have grown about 2-3 inches long.
    Note : Growth depends on room temperature. Please check notes below,
  • Refrigerate in an air tight bag and use within 3 days.

Notes

  • Please check the video for a visual guide. 
  • It is easier to grow sprouts in warmer temperatures of above 70F/21C.
  • In winter, place the beans in a warm spot to encourage sprouting. I turn my oven on for two minutes, turn it off and place the beans in. 
  • To grow the longer kind of sprouts,
    • use a colander or anything else with drainage holes. I use my two tier steamer
    • Remember to rinse the sprouts twice everyday for ideal growth.
    • Remember to discard the water collecting in the drainage bowl to avoid the growth of harmful micro organisms.  
    • Remember to place the colander in a dark spot .
  • Use caution when using raw sprouts, personally I use the shorter sprouts raw, but I always blanch the longer sprouts that have been growing for 3-7 days
At an indoor temperature of about 80F/27C
  • Short sprouts grow in 24 hours(after soaking) 
  • Longer sprouts take 3 whole days(after soaking) 3 x 24 = 72 hours
Here is my timeline. Note that growth can be faster or slower depending on temperature. 
Tue evening - soak beans
Wed morning - drain and let them begin sprouting.
Thursday morning - short sprouts are ready.
Saturday morning - longer sprouts are ready. That calls for Pad Thai or fried rice for the weekend! :)
