Practical
Consumer tips
- 1
Always check your medication labels for grapefruit warnings; Pomelo is usually a safe substitute.
- 2
When peeling a Pomelo, score the thick rind deeply to make removal easier, and make sure to discard all the bitter white pith.
- 3
If Grapefruit is too tart, try broiling it with a tiny drizzle of honey to caramelize the natural sugars.
- 4
Keep both fruits refrigerated; they lose moisture and flavor quickly at room temperature once cut.
