Choosing ripe mangoes is crucial for the best flavor. Look for mangoes that yield slightly to pressure and have a fruity aroma at the stem end. Avoid mangoes with wrinkled skin or those that are too soft or mushy. The Ataulfo (Honey or Champagne) mango is best for mango habanero sauce due to its sweet, rich flavor and smooth, buttery texture. Other options include Haden and Kent mango.
