Why it happens

Main causes

  • Thermal shock
    A sudden temperature difference between cold tomatoes and hot liquid causes the skin to crack.
  • Delicate skin
    Some varieties or very ripe tomatoes have fragile skin and crack easily.
  • Tight packing
    Tightly packed jars increase pressure during heating and cause cracking.
