Creating Mango Sago can be a joyful experience if you follow these straightforward steps:

1. Cook the Sago: In a saucepan, bring 4 cups of water to a boil. Add the sago pearls and cook on medium heat for about 15-20 minutes, or until they turn translucent. Stir occasionally to prevent sticking.
2. Wash the Sago: Once cooked, drain the sago pearls in a fine sieve. Rinse them under cold water to remove excess starch and cool them down.
3. Prepare the Mango: While the sago is cooking, peel and dice the ripe mangoes. Set aside a few pieces for garnishing later.
4. Mix the Coconut Milk: In a separate bowl, combine the coconut milk and sugar. Stir until the sugar dissolves completely.
5. Combine Ingredients: In a large bowl, mix the cooked sago pearls, diced mango, and coconut milk mixture.
6. Chill the Dessert: Cover the bowl and refrigerate for at least 30 minutes to let the flavors meld together and the dessert to cool.
7. Serve: After chilling, scoop the Mango Sago into individual serving bowls and garnish with reserved mango pieces.

These steps will guide you in effortlessly creating this incredible dessert.
