To really get the most out of the combination, don’t be shy. For four servings of Angostura whipped cream, pour ½ cup chilled cream into a bowl, add 1 to 2 teaspoons light brown sugar (white sugar is fine, too, but brown adds a little something extra) and about 12 dashes Angostura bitters. Whisk the mixture until it thickens enough to scoop and dollop. Spoon over each slice of pie—or a warm brownie, a holiday ice cream sundae, or anything else that might be enhanced by warm spice and fluffy sweetened cream.
