Equipment

  • large pot
  • Large bowl
  • Tongs
  • Serrated knife
  • Freezer bags

Ingredients

  • 6 ears sweet corn

Instructions

  • Remove the husks from the corn. Inspect the cobs and pull off any remaining silks. Use a knife to cut off any bruised or shriveled areas.

Corn off the cob with blanching (my preferred method!)

  • Bring a large pot of water to a boil. Drop the prepared corn cobs into the water and cook until bright yellow, about 3 to 4 minutes.
  • Use tongs to remove promptly and transfer to a large bowl filled with ice water. Let them cool for about 4 minutes. Drain and pat dry.
  • Slice the kernels off the cobs, using a serrated knife for best results. Consider slicing the corn in a bowl to prevent the kernels from going all over the place.
  • Transfer the blanched kernels to a freezer bag. Seal tightly and remove as much air as possible.
  • Label and store in the freezer. Use within 8 to 12 months. Add directly from frozen to hot dishes. Thaw before using in salsas or salads.

  • Transfer to a freezer bag. Seal tightly and remove as much air as possible.

Corn in the husks

  • Do not remove the husks. Wrap each ear tightly in a couple layers of plastic wrap.
  • Transfer to a freezer bag. Seal tightly and remove as much air as possible.
  • Let thaw before cooking, either in the fridge overnight or in a bowl of cool water on the counter (keep in plastic wrap/bag while thawing).
  • Remove husks once thawed and cook as desired, such as in boiling water for 3 to 5 minutes.

Notes

  • The amount of kernels per cob varies depending on size. Typically, each ear of corn yields about ½ to ¾ cup.
