Sprouting in a Mason Jar


There’s a wonderful old Chinese Proverb: “If you would be happy all your life, plant a garden.”

Growing Sprouts in a Mason Jar

Day 1

which would explain why growing even small things on my windowsill so reliably lifts my spirits. I’ve added another mason jar to my windowsill this week along side the jar of green onions I told you about in Growing Green Onions in Water. Who knew? This week we sprouted alfalfa seeds purchased from a local health food store. They weren’t an easy find in my area but you can order sprout seeds at an online retailer such as Sprout People.

Sprouting Sprouts in a Mason Jar

Day 3

Start with 1-1/2 to 2 tablespoons of seeds of your choice, and there is quite a lot to choose from. You can sprout alfalfa sprouts, bean sprouts, lentil sprouts, delicious spicy radish, sunflower and many more! Broccoli sprouts are especially known for their healthful properties, containing 30 to 50 times of the concentration of isothiocyanate, one of the healthy compounds in broccoli, that exists in the mature plant! So nutrient-wise, you sure get a bang for your buck with sprouts.

First, soak your seeds in a 2% bleach solution, ( 1 teaspoon bleach to 1 cup water) for 15 minutes to kill any harmful bacteria. Rinse well and soak the seeds in plain water overnight. The next morning, drain the seeds and place them in a mason jar. There are mesh lids made just for sprouting, or you can just replace the center part of the mason jar lid with cheesecloth or loosely woven muslin to allow air to circulate and excess water to drain. Twice daily, rinse and drain the seeds, placing your jar upside down within a bowl or tray to catch drainage. Within about 5 days, you can expect plump and flavorful alfalfa sprouts. On the last day, place them in in a bright area, (not direct sun), being very careful not to let them dry out. This allows chlorophyll to form, which will cause them to become that healthful green color.

    I need to start sprouting again! I love sprouts!

    But I’ll skip the soaking in bleach. it’s a known corrosive and will just do more damage. Did you know that women at home who use bleach are 54% more likely to get cancer? You may want to do your research before continuing with bleach… (http://www.pristine-water.com/Chlorine%20Hazards.htm)

      Hi Andi,
      Thanks for your input on this. We understood that the use of a bleach soak could raise some eyebrows, but given the real and serious threat of e coli contamination, felt it was responsible to pass on the recommendations of the sprouting retailers. Of course, it’s up to you what you decide to do in your own kitchen and we appreciate your point of view. Thanks for the comment!

    Soak in bleach!!!! surely not. I would soak first with 2 drops of Young Living essential oil in a cup of water – known to kill 99.9% of bacteria in such instances. But!! the Young Living essential oil is a therapeutic essential oil and can actually be ingested – also to kill internal parasites – so maybe you should reconsider soaking in bleach and turn to an essential oil – that will do the job well.

      Well, like we said, Suzanne – we’re just passing on the instructions from the seed retailer. You, of course, are welcome to forgo their advice and soak in anything you like. :-)

    I totally agree with the bleach solution.
    It may seem a little harsh, but I’d rather be safe.
    Thanks for the info.

    I was wondering if you could soak them in vinegar + water? I wash all my fruit and vegetables this way. It’s supposed to kill bacteria. It sure makes my fruit & veggies last longer.

    I can’t wait to try the sandwich recipe! Yum
