2 cups store-bought eggnog
2 cups amaretto liqueur
2 cups vodka
Combine the eggnog, amaretto and vodka in a pitcher and chill at least 30 minutes.
Crush gingersnaps in a food processor until they almost resemble a fine powder. Pour a tiny amount of amaretto into a small dish. Using your finger tip dipped in the amaretto run it around the rim of a chilled martini glass. Dip the wet rim of the glass into a dish where the crushed gingersnaps have been placed. Pour the alcohol mixture into prepared glasses and sprinkle with ground cinnamon and fresh grated nutmeg.
