Storage Tips

  • •Store in the crisper drawer of your refrigerator to extend shelf life for up to three weeks.

How to Pick the Best One at the Store

Selection Tips

  • •Choose fruit that feels heavy for its size, which indicates a high juice content.
  • •Look for firm, smooth skin that is slightly soft to the touch rather than rock-hard.
  • •Avoid fruit with soft spots, deep indentations, or patches of mold near the stem.
  • •Look for a bright, vibrant color on the rind, as deep hues often indicate a sweeter, more flavorful interior.

Frequently Asked Questions

Does grapefruit interact with my medication?

Yes, grapefruit contains compounds that can interfere with how your liver processes certain medications, such as statins or blood pressure drugs. Always check with your doctor if you are taking prescription medication.

How can I make grapefruit less bitter?

The bitterness is primarily found in the white pith. If you segment the fruit carefully, removing as much of the pith and membrane as possible, you will find the flavor much sweeter.
