Notes
Can we use canned or frozen pineapple?
Fresh pineapple would taste the best in this frappe but if you can't get your hands on the fresh ones you can definitely use frozen or canned ones. Drain and wash canned ones before using them. The frozen pineapple you can use directly.
Don't we need any sweetener?
The natural sweetness of pineapple is absolutely perfect for this recipe. However, if your pineapple is not ripe enough you might want to add some sugar or honey to it.
Can we add mint extract instead of mint leaves?
Mint leaves will provide this refreshing flavor and freshness in the drink. You may use mint extract but would suggest using fresh mint leaves instead.
