1. Lay a whole pineapple down on a large cutting board. Use a sharp knife to cut about a half inch off the bottom end. Then cut off the top of the pineapple and discard.
2. Place one cut, flat-side of the pineapple on the cutting board. Position the knife where the yellow flesh meets the outer rind and make a cut down the outside of the pineapple removing the rind, following the contour of the fruit. Repeat this process as you work your way around the pineapple until you have only the yellow inside remaining. 

Spears

1. Leaving the pineapple standing vertically, make a cut down the center splitting it in half lengthwise. 
2. Keeping each half standing vertically, cut in half lengthwise again creating two quarters. Repeat with the other half of pineapple to create a total of 4 quarters.
3. Stand up each quarter on the cutting board and cut down the pointed inside corner to remove the core. Repeat with all four quarters.
4. Take one of the quarters and lay flat on the cutting board.
5. Make 1/2 inch slices lengthwise so you have 3 pineapple spears. 
6. Continue this process with the other pineapple quarters, until they are all cut into spears.

Chunks

1. Leaving the pineapple standing vertically, make a cut down the center splitting it in half lengthwise. 
2. Keeping each half standing vertically, cut in half lengthwise again creating two quarters. Repeat with the other half of pineapple to create a total of 4 quarters.
3. Stand up each quarter on the cutting board and cut down the pointed inside corner to remove the core. Repeat with all four quarters.
4. Take one of the quarters and lay flat on the cutting board.
5. Make 1/2 inch slices lengthwise so you have 3 pineapple spears.
6. Holding the 3 pineapple spears together on the cutting board, make 1 inch cuts perpendicular to the previous cuts moving from one end of the spears to the other. This will result in pineapple cubes. Repeat process with remaining pineapple.

Circles

1. After removing the ends and outside rind, lay down the pineapple horizontally on the cutting board.
2. Using a sharp knife move from one end of the pineapple to the other cutting the pineapple into 1/2 inch circles. Move down the entire pineapple until it is all cut.
3. Now place each circle on the cutting board and carefully use a small, paring knife to cut around the inside core of each piece. Continue this process with all the pineapple circles until all of the core pieces have been removed and discarded.
