Cut agar agar into small strips in case if its a big sheet like. Measure and take agar agar in a sauce pan, add water to it.
Heat it up. Keep stirring and cook in low flame. Cook until it is completely dissolved and the water is clear without any strips. Switch off and set aside to cool down a bit.
Take chopped mangoes in the mixer jar, add sugar to it and make a puree.
Add the puree to china grass mixture. Mix well.
Keep a glass tilted on a muffin pan. Pour mango agar agar mixture till half of the glass is reached. Set aside to set.
Now take milk in a container. Add fresh cream to it. Add sugar and vanilla essence to it.
Mix well until sugar dissolves completely. Transfer the mixture to a pan, allow for a gentle boil. Switch off and add it to china grass mixture.
Whisk it well and pour to the glass as second layer making sure the first layer is set completely. Touch and see if it doesn't stick then its set you can pour. I just set the remaining in silicon muffin liners.
Chill it until serving time. Serve and Enjoy Mango Panna Cotta!.
