Choose your substitute based on your dish: salad/slicing needs crisp fruit; cooked dishes can handle fruitier swaps.
Use the listed ratio (1:1 or the adjusted ratios) and cut the substitute to the same size as your asian pear.
If your swap tastes too flat or not “fruity,” add a small brightener (lemon/lime juice) and taste again.
For soft substitutes (like pineapple or cucumber), reduce the amount and keep pieces larger so they don’t disappear.
Chill crisp swaps (apple, jicama) for 10–20 minutes so they stay snappy during serving.
