Jam Making Tips

  • Use slightly underripe fruit for higher natural pectin
  • Test for gel by placing a small amount on a frozen plate
  • Skim foam for clearer jam
  • Process in water bath for 10 minutes for shelf stability
  • Low sugar recipes require special pectin - regular pectin won't set properly
