The availability of mangoes will vary depending on where in the world you like. In North America, the most common varieties are Tommy Atkins (large and orange/red when ripe) and Ataulfo (medium-sized, yellow, and kidney-shaped). I highly recommend using Ataulfo over Tommy. Sweeter and more flavorful! If you can find Alphonso (King of Mangoes) or Carabao, those will taste the absolute best.
