In a medium heat-safe mixing bowl add one can of evaporated milk and stir in 4 envelopes of gelatin, set aside.
Mix well and let this mixture stand for 5 minutes.
In a sauce pan, pour in 2 cans of evaporated milk and whipping cream, bring to a boil slowly.
Once it has started to boil add sugar, salt, and amaretto and stir until everything is dissolved.
Place a fine mesh strainer over the bowl with the gelatin-evaporated milk mixture.
Remove the saucepan from heat and carefully pour boiling milk mixture into the gelatin-evaporated milk mixture.
Stir in vanilla extract.
Add a little tiny touch of black food coloring for a "greyish" hue. This is so it looks more like "Grey Matter"
Pour the grey matter mixture into your brain mold and refrigerate overnight.
Top with the Blood Glaze just before serving.
