Grapefruit

Grapefruit is a fruit whose cultivar, ripeness, storage and preparation determine sweetness, acidity, aroma and texture.

What Is Grapefruit?

Grapefruit is Citrus × paradisi, a large citrus available in white, pink and red-fleshed cultivars. It is valued for bittersweet citrus flavor with pronounced acidity and floral peel aroma.

How to Choose

Choose heavy fruit with firm sound skin and no mold or deep soft spots. Avoid mold, fermented leakage, deep soft rot or unexpected off-odors.

Storage and Safe Handling

Keep it refrigerated for longer storage; wash before zesting or cutting. Wash fresh fruit under running water before cutting or eating and prevent cross-contamination from raw animal foods.

Preparation and Culinary Uses

Useful approaches include: segment, juice, brûlée, use zest in sauces and desserts, or pair with seafood and bitter greens. Match technique to ripeness, acidity, water content and firmness.

Best Flavor Pairings

Grapefruit works particularly well with avocado, seafood, fennel, mint, honey, gin-style botanicals and yogurt.

Substitutions

A practical substitute is pomelo or orange plus lemon for flavor balance, though bitterness differs. Adjust sugar, acid and moisture because fruits behave differently.

Common Mistakes

• Choosing by color alone without considering cultivar.
• Storing delicate fruit wet.
• Using underripe or overripe fruit for the wrong technique.
• Substituting without adjusting acidity and water content.
