Whole Lettuce Head

• 1). Shave about 1/8 inch off the bottom of the lettuce head stalk with the knife. Take off just enough to remove the old, dry end.
  
  
• 2). Soak the stalk in a bowl of lukewarm water for about half an hour, being careful not to fully submerge the lettuce head, just the stalk.
  
  
• 3). Refrigerate the lettuce and after about two hours the leaves will have revived and attained their former crispy state.
  
  

Picked Lettuce Leaves

• 1). Fill a bowl one-quarter full of ice and one-quarter full of water. Mix to make the water icy cold. Leave for about 10 minutes until some of the ice melts into the water. Remove the ice.
  
  
• 2). Submerge the lettuce leaves in the icy water, leaving them in only for about 30 seconds to a minute.
  
  
• 3). Remove the lettuce leaves gently from the ice water and place in a plastic bag. Don't shake the leaves, as some of the ice water should remain on them for the best effect.
  
  
• 4). Place the plastic bag, loosely sealed at the top, into the refrigerator. Wait three hours and the lettuce leave will have revived and be crispy, ready for use.
