Burnt Sugar Ice Cream

Directions

1. 1
   3. Remove 1/2 cup hot milk mixture from saucepan and add slowly to beaten egg yolks while whisking vigorously. Whisk this mixture back into saucepan. Over low heat, cook mixture until it reaches 180 degrees on an instant-read thermometer, stirring constantly (about 5 minutes). Custard should not boil or bubble. If mixture starts to give off a fair amount of steam, take off heat for a few moments and stir vigorously.

   4. Combine remaining 1/2 cup sugar with 1/4 cup water in small saucepan over medium heat. Do not stir but swirl pan vigorously until sugar dissolves. Increase heat to high and bring syrup to boil. Cover and cook for 2 minutes. Uncover and continue to cook until syrup takes on color. Swirl pan constantly at this point, moving pan off and on heat to slow down cooking. Remove from heat when syrup is dark and mahogany-colored. Pour into custard mixture (make sure there is a lot of extra room in the saucepan-the custard will bubble and froth) and whisk for about a minute. (The sugar syrup will harden at first and then dissolve as you whisk.)

   5. Pour custard through fine-mesh strainer into nonreactive bowl. Remove vanilla pod from strainer and add to mixture. If using vanilla extract, add it to the custard now. Place bowl into a large bowl filled halfway with ice water to cool. When mixture reaches room temperature, cover bowl with plastic wrap and refrigerate. It is best to refrigerate mixture overnight or for at least 6 hours.
