Rinse the inside of a quart-sized glass jar. Dump a tablespoon or two of alfalfa seeds into the bottom of the jar. Add enough clean, cold water to cover the seeds. Soak the seeds for three to four hours, then drain them.
Place a piece of gauze across the top of the jar and secure it with a string tied around the rim, or an elastic band. Place the jar at a 45-degree angle to ensure good drainage of the water, reducing the risk of molding. Make sure the jar is not positioned in direct sunlight.
Rinse and drain the sprouts in the jar each morning and each evening for four to seven days, until the sprouts have developed at an acceptable length. Roll the jar periodically during the sprouting process so that your sprouts do not get tangled.
Refrigerate your fresh sprouts for two to three days. Wash the jar thoroughly before you create another batch.
