Wash and peel the ripe soursop and place the pulp in a small pot or bowl. Add a little water (about ¼ cup) to the pulp. Using the back of a fork mash the pulp a bit.

Place the pulp in a strainer and continue pressing with the back of a spoon to separate the pulp from the seeds. Add water to pulp; mash then strain. Repeat this step until all the pulp has been removed from the seed.

Pour the tin of condensed milk into the soursop pulp and stir. Then add 1 ½ cups of milk and continue stirring. Add the bitters and almond essence and stir. Pour in a mug and serve chilled or with ice.
