-In the bowl of an electric mixer fitted with the paddle attachment, mix the egg, egg yolks, and the orange zest, ½ cup of the sugar, vanilla, and orange liqueur together on low speed until just combined.
-Preheat the oven to 300° (F), 150° (C).
-Meanwhile, scald the cream in a small saucepan until it’s very hot, but not boiling. With the mixer on low speed, SLOWLY add the cream to the eggs.
-Carefully pour the mixture into 6 (8 oz) ramekins until almost full. Place the ramekins in a baking pan and carefully pour boiling water into the pan until it comes halfway up the sides of the ramekins.
-Bake for 40 – 45 minutes, or until the custards are set when gently shaken. Remove the custards from the water bath and cool to room temperature. Then refrigerate until firm and ready to serve.
-To serve, sprinkle one tablespoon of sugar evenly on the top of each ramekin and heat with that little kitchen blowtorch until the sugar caramelizes evenly. Allow them to sit at room temperature for a minute until the sugar cools, hardens, and will crack wonderfully with a spoon when you dig in!
