In a food processor, add the cut mangoes and maple syrup to make a mango pureé. Measure out the mango pureé, as it should be enough for one cup.
In a pan, mix 1 teaspoon of agar and 150 ml of water. Turn the heat to medium-high and bring to a boil while whisking regularly. Once it starts boiling, bring the heat down to low-heat and continue stirring for about 4-5 minutes until the agar has dissolved completely.
Once you've confirmed that the agar is dissolved, pour half a cup of coconut milk and continue stirring. I did not add coconut milk earlier as it would make it impossible to see if the agar had dissolved.
Pour the mango pureé into the mixture using a sieve. By using the sieve, you prevent mango fibers from getting into the mixture.
After incorporating the mango purée, add the lime juice and mix for another 3 to 5 minutes, until you get a creamy, shiny consistency.
Pour the mixture into dessert bowls and let it cool down before placing it in the fridge to set for 4-5 hours.
Once it's ready to eat, you can garnish it with coconut milk, diced mangoes, and even lime zest.
