1/3 cup heavy creamPour the cream into a small, heavy saucepan. Split the vanilla bean in half lengthwise and use the tip of a sharp knife to scrape the seeds from the pod halves into the cream. Place over medium-high heat and bring to just under a boil, stirring occasionally. Reduce the heat to low to keep the cream warm.
1/4 of one vanilla bean
1/2 cup sugar
2 Tbs cup water
1/8 tsp salt
1 Tbsp light corn syrup
1/4 tsp lemon juice
2 Tbsp unsalted butter
In a medium, heavy saucepan, combine the sugar, water, salt and corn syrup. Use a good-sized pan because the caramel will boil vigorously and the volume will increase dramatically as soon as the hot cream is added. Bring to a boil over medium heat, stirring to dissolve the sugar. Then let the mixture boil, without stirring, until the mixture is amber colored. Watch the sugar mixture carefully as it cooks to avoid burning the sugar. From the time the mixture started to boil, it took over 15 minutes to reach an amber color. Remove from the heat.
The mixture will continue to cook off the heat and become darker, so make sure to have the cream close by. Carefully and slowly add the cream to the sugar syrup. The mixture will boil vigorously at first. Let the mixture simmer down, and then whisk until smooth. Add the lemon juice and let it cool for about 10 minutes.
Cut the butter into 1-inch chunks and add them to the caramel one at a time, whisking constantly after each addition. Then whisk the caramel periodically as it continues to cool.
Pour the caramel sauce in an airtight container such as a glass jar and store in the refrigerator. This will keep for up to a month.
