Yes, frozen pineapple is just as delicious and nutritious as fresh pineapple. And, at certain times of the year, it is even more flavorful than fresh pineapple! Frozen fruits are harvested in season at peak ripeness to ensure they have an intense flavor and juicy consistency at the time of freezing. Fresh pineapple may not taste as juicy and vibrant during the off-season compared to when it's in-season, which is why frozen pineapple would be a better choice at that time.
