Here's my recipe, don't tell anyone, it's a secret.
In a large blender, about 7 cups or 1.75 liters, combine the following:
The flesh of 2 large or 3small Avocados, two pinches of salt, 1/2 can(7 oz) sweetened condensed milk, 1/3 cup sugar, two cups milk.
Blend all of this together at the fastest setting until everything is mixed and the Avocado is completely emulsified. Once everything is emulsified, not before, add about 3 cups ice and break the ice into whatever size you prefer, I pretty much emulsify it.
This is the sweet version and you can cut back on the sugar if you want it less sweet or you can add more sweetened condensed milk in place of the sugar but this recipe is a great starting point and you can adapt it to your personal preference.
The secret to this recipe and recipes containing coconut like coconut ice cream is the two pinches of salt that brings out the flavor of fruit that isn't very strong to begin with. If anyone reading this has not tried an Avocado smoothie, I highly recommend it!
Jeff, I think it's time for you to plant another Avocado, for your wife of course.
