Wash and peel the lucumas. Cut them in half and discard the seeds. Chop the pulp.
In the vase of the blender put the lucuma, condensed milk, evaporated milk, and vanilla, and process until smooth. Transfer to a bowl.
For a completely silky texture, pass the lucuma mixture through a sieve.
Whip the heavy cream until it looks like yogurt, and combine with the lucuma.
Pour into a pyrex or any other container. Cover with plastic film and freeze for at least 4 hours or until firm. It can be done the day before.
To serve, cut in individual portions, put in serving plates, cover with fudge, sprinkle some chocolate cookie crumbs, mint sprigs, and add whipped cream, if desired.
Serve immediately.
