First, clean the mangoes, peel them, and cut them into chunks.
Add chopped mangoes, applesauce, maple syrup, or agave, lemon juice, and ginger in a blender. Continue with mixing until it becomes smooth. Set aside.
Mix agar powder in a small bowl or pot with cold water. Pour the mixture into a small saucepan over medium heat and start boiling it. Stir the agar mixture constantly with a whisk. Once the agar has dissolved in the water, you will get a smooth jelly-like texture.
Add mango puree to the agar mixture and stir to mix them until the mixture starts to bubble.
Take it out from the heat and pour it into molds or cups and let it chill for 2 hours.
You can serve it immediately or keep it in the refrigerator for later.
You can serve the mango pudding with some coconut whipped cream, berries or dry fruits or mango cubes on top for decoration.
