Food 52 Corn Chowder Recipe Can this chowder be kept warm in a crock pot or on low on the stove top until serving. Also, can leftovers be frozen.

I guess you want to make corn chowder ahead, and serve as part of a buffet for
a big group at dinner.
Two separate questions.
Yes, the soup can be made ahead and frozen (most chowders hold up OK in freezer for 1-2 months).
No, probably slow cooker won't hold it at safe temperature for several hours.
For safety when serving, the soup should be 135F or higher, or cooked again to 165F or more after two hours.
See two useful articles.
