Tips

  • Keep refrigerated.
  • Freeze in airtight container and leave at least 1/2 inch headspace at the top, as buttermilk will expand when frozen.
  • Frozen buttermilk will have a slightly different taste and texture when thawed and is best used in cooked dishes.
  • Freezer time shown is for best quality only— foods kept constantly frozen at 0° F will keep safe indefinitely.
