The Step of Jar Method 1.For a quart-sized jar, start with 1 1/2 table spoons seeds inside the jar, screw on the fine mesh sprouting lid and partially fill the jar through the sprout jar lids with warm water, not hot 2.Swirl it around to clean the seeds, then pour out. Refill with warm water to cover at about 3 times their depth let soak overnight, away from light. This gets the germination process started 3.Pour off the soak water. Find a location that is not exposed to direct sunlight. Place drained jar propped at angles allow any extra water to drain out. Turn the jar to spread out the seed. Cover the jar with the sprout jar lids and a dishtowel and leave for 3 to 4 hours. 4.Rinse sprouts with cool, fresh water 2 or 3 times each day until they are ready to eat or refrigerate. When they begin to throw off the seed hulls, let the jar with sprout jar lids installed overflow with the water and the hulls will float out the top through the sprouting lid screen. Turn the jar to spread out the seed each time you rinse 5.Pour the sprouts into a pan or sink of clean water. Skim off any remaining hulls that float to the surface. Other hulls will fall to the bottom of the container. Pull out the sprouts, gently shake off excess moisture and drain in a colander 6.Please Note:Special attentionDo not place them in salt water, and keep dry.
