After trimming, dump into boiling water and count exactly 3 minutes....use your iPhone timer!
Immediately remove to a cold water bath. Stir up a bit now and then to cool as fast as possible. They can stay there until you're ready to package. Drain and pack in plastic freezer baggies, squeezing as much air out as can as you zip closed. Don't forget to put the date on the outside of the bag!
Ahhhh....the taste of summer during next winter! You can't beat that!
