Sprouts of nuts, beans, and seeds were a dietary staple for over 5,000 years and still remain so in many Southeast Asian diets. After making international headlines for recent bacterial contamination, sprouts have received increased attention. The U.S. government even has a webpage dedicated to what consumers should know regarding the safety of sprouts.
Like other produce and meats that are properly handled, sprouts can offer nutritional benefits that supplement diets. And, they are easy to grow using a variety of methods. Five popular ways to grow sprouts for consumption are using trays, soil, a jar, a hemp bag, and paper towels.
Trays are available for purchase that will make your first sprouting experience an easy one. After obtaining your tray, soak the sprout seeds overnight in a jar or bowl. Use three times as much water as seeds. Since your sprouting tray has holes at the bottom, you can simply dump the soaking seeds into the tray. Attempt to spread the seeds fairly evenly along the tray floor, but understand they will move anyway once rinsed (which you should proceed to do next).
After rinsing, assemble any other parts of your tray (cover and/or drip tray) and place in a dark spot. During this sitting period, rinse the seeds 2-4 times per day. Within a day or two, you will see some sprouts and within 5-8 days, you will see larger sprouts. Once your sprouts have some little leaves and are an optimal length for your needs, move the tray to a sunny location. In a few hours, the sprouts will green and will be ready to eat. Store uneaten portions for up to a week in the refrigerator.
Sprouts can be grown using a traditional soil method, and some feel this is the safest method due to excess moisture which may encourage bacteria or fungi. Soak your sprouts overnight in a jar, ensuring lukewarm water covers all the seeds. Fill a shallow dish or pot with some light potting soil, drain your seeds and place a layer within moist soil. Cover with more moist soil and cover the entire container with plastic wrap.
Place the container in a warm, dark spot. Sprouts will begin to appear in 3-5 days. When they are long enough, you can cut with scissors and use immediately. Uncut sprouts will continue to grow and can be harvested later.
Choose a clean jar, such as a mason jar, glass container, or pickle jar. Fill the jar with enough filtered water to cover the seeds themselves. Enclose the jar with a cheese cloth or mesh barrier (nylon stockings or an old window screen will work). If you still have the metal ring that came with a mason jar this can easily keep the cover in place. Let sit overnight; then drain the water and rinse sprouts twice per day, thoroughly draining the water after each rinse.
Keep an eye on the jar’s environment. Temperature should remain between 50-70 degrees Fahrenheit and the jar can remain in a dark spot. When the sprout grow to your preferred length, you should properly drain and clean them. Use immediately, but may be refrigerated for up to five days.
Hemp bag sprouting
Although any sprout will work, beans and grains are perfect for sprouting in hemp bags. The reason for this is that the sunshine greening step utilized in other sprouting methods isn’t practical through a hemp bag. You can either buy a hemp bag or make one yourself (see link below for instructions).
First, soak seeds overnight in a jar or bowl, making sure the water entirely covers the seeds. You’ll want to prep your bag before use, boiling it for at least five minutes. This will remove any trace fabrics. Next, pour your seeds directly from the jar into the bag, as the soaking water will filter right out. Rinse your sprouts 2-3 times per day by dunking the entire bag into water and letting it drain. After each rinse, close the bag and let it sit (you may want to put a drip tray underneath or hang it over a sink).
You get to decide when the sprouts are ready to be eaten, determined by their length and growth time. If storing in the refrigerator, you can do so directly in the bag, but make sure the bag isn’t soaked from rinsing. Best of all, your bag is reusable! Simply rinse with hot water (no soap) and hang dry.
Sprouting between paper towels
A very simple method for growing sprouts is between two paper towels. As with other methods, sprouts should be soaked in water overnight in a jar or bowl. After rising, arrange seeds thinly between two paper towels. Towels should be moistened often so as to prevent a dry environment. Once sprouting starts, simply grow to your desired length and snip with scissors to garnish salad, soups, or the main course. Be careful not to oversprout; seeds may eventually mold or stick to the paper towels.
