Making sure to pick a mango that is ripe but not too ripe (and soft), makes all the difference. Mangoes have a flat oval-like pit in the center of it. You know you are cutting through it because the knife will give you resistance, where as cutting through the mango itself is like butter. Start by cutting the sides of the mango away from the pit - you’ll be cutting off center on each side as opposed to straight down the middle. Then, while placing the mango half (mango side down) on your cutting board, simply use a sharp knife to cut the peel away from the outside of the mango. Place the peeled mango half, flat side down, on a cutting board and dice!
