The pineapple is a juicy sweet tropical fruit native to Brazil. This fruit of a bromeliad plant is eaten throughout most of the world. Pineapple is typically served fresh but it can be grilled or pan fried.
In addition to fresh pineapple you can easily find it canned in slices, chunks or crushed. You can also purchase frozen pineapple chunks or "tidbits" which are little pieces. These products are all readily available in most well-stocked grocery stores including Walmart.
You can also purchase pineapple extract which can be used to either enhance or replace pineapple in recipes including baked goods and smoothies. Look for this in the spices/baking section of your grocery store. You can also purchase it online at Amazon.com: Pure Pineapple Extract
