Prepare the hard-boiled eggs by cooking for 15-17 minutes. See cooking tips below.
In food processor or blender, put egg yolks, garlic, and lemon juice while the eggs cool. Slowly add truffle oil, olive oil, and grape-seed oil to form an emulsion. Season to taste and refrigerate.
With a fork, mash the dozen cooked egg yolks and blend thoroughly with 1/2 cup of truffle emulsion. Add more to taste if desired. Pipe or fill the hard boiled egg whites with the egg yolk mixture. Refrigerate until cool or up to 6 hours. Serve with finely chopped parsley or minced chives as a garnish.
