Notes
Dry the fruits: Always pat dry the fruit before cutting to prevent a soggy chaat. It also ensures that the seasoning sticks to the fruit pieces and doesn't slip off.
Fruit choices: You can customize this recipe by picking your favorite juicy, firm fruits. Avoid watery fruits like watermelon that can water down the entire chaat. Avoid delicate berries that may get squished while tossing the salad.
How to prevent browning: Fruits like bananas, apples, and pears are best cut when ready to serve since they start browning after cutting due to oxidation. You can cut and assemble other fruits like mango, strawberries, grapes, and oranges 2-3 hours ahead of time.
Making Ahead: When making this ahead, cut fruits like bananas and ripe pears towards the end so they don't get mushy.
Cutting Size: For best results, cut all fruit into bite-size pieces for even seasoning.
Season: Toss the fruits with seasoning just before you are ready to serve; otherwise, the fruits will begin to soften and break down.
