shallow pan. Hi I made a ham for our family Christmas dinner, actually I made two, large family. I ended up with a lot of ham left over(one half of a large ham). That is a good thing. I am now making a brunch for my children (Ukrainian Christmas) on Saturday this week. Is there a way to re-heat this ham without having it come out dry, without adding anything extra to it?? Thanks Cooked ham can be stored in the refrigerator for 4 to 5 days. Reheat sealed in a foil packet. Can I cooked some guinea fowl supremes (grilled in the pan and cooked in the oven at 400 degrees F for 15 to 20 minutes depending of their size; refrigerate them and warm them up the day after for dinner?  If so, at what temperature and how to do it(sauce covered?) to avoid them from drying?  Thanks! This is a safe thing to do if the supremes are completely cooked to a safe temperature of 77C/170F measured with a food thermometer. Then if they are spread in a shallow container and refrigerated promptly; covered when cold. Reheat quickly to 77C/170F. Cover to prevent dryness and you may want to add a small amount of chicken broth to the pan. I bought fresh un-cooked chicken breasts on Monday with the intent to marinade them overnight and eat on Tuesday evening, however I had a last minute change of plans Tuesday and was unable to cook the chicken breasts.
