Step 1

Saute: Heat oil in a saucepan over medium heat, then saute garlic, onion, and ginger until onions are slightly translucent, about 5 minutes.

Step 2

Simmer: Add the onion mixture to a large pot along with the rest of the ingredients. Stir well and bring to a gentle simmer over medium/low heat. Cook uncovered for 1 hour, stirring occasionally.

Step 3

Mash: Mash with a fork or potato masher to break down remaining large mango chunks (smaller pieces are fine). Serve warm or chilled.
