Caramel Custards

Preheat oven to 325 degrees. Heat sugar and water in a saucepan over medium-high heat, swirling occasionally, until deep amber, about 7 minutes. Carefully whisk in milk and cream.

Whisk together yolks, vanilla, and 1/4 teaspoon salt. Slowly pour caramel-milk mixture into yolk mixture, whisking constantly. Skim any bubbles from the top. Divide evenly among four 6-ounce ramekins.

Set ramekins in a 9-inch square baking dish. Pour boiling water into dish to come a third of the way up sides of ramekins. Bake until custards are just set but jiggle slightly, 27 to 30 minutes. Remove from water using tongs. Refrigerate for 20 minutes.
