From Gardening When It Counts–
“It’s especially helpful to chit peas and beans when you’re sowing early, in soil not yet quite warm enough. Presprouting indoors preserves a lot of the seed’s energy to help it get past the harsh conditions outdoors.
Count out three seeds for every plant you’ll ultimately want, and put them in a glass jar. Soak in tepid water for no more than six to eight hours. Attach a circular piece of plastic fly screen over the mouth of that jar with a stout rubber band.

Then drain the water, rinse with tepid water, and drain immediately and thoroughly. Place the jar on its side near the kitchen sink. Room temperature should exceed 65 degrees. Twice a day, gently rinse with tepid water and drain.
In three to four days, roots should be emerging. Plant them outside before the rapidly developing (and brittle) roots grow longer than the seeds. In each spot, you’ll want to plant to grow, gently place at least two sprouting seeds about 1 1/2 inches deep, if possible with the root pointed down. Cover with loose soil. They’ll be up and growing in a few days.”
