Makes About 1 Pound

Choose A Stainless Steel Bowl that fits inside a large saucepan without touching the bottom of the pan. Add water to the pan and place the bowl in the pan so that the bowl touches the surface of the water but still sits firmly on the rim of the pan. Remove the bowl, place the pan on medium heat, and bring the water to a boil. Place the cream in the bowl and place over the boiling water. Adjust the heat under the pan to medium and heat the cream, checking the temperature often with an instant-read thermometer, to 190F; stir occasionally. Stir in the vinegar, continuing to stir gently until the cream begins to curdle. Remove the pan from the heat, cover, and allow the curds to firm up for 10 minutes. Line a strainer or colander with dampened cheesecloth, napkin, or coffee filters. Set the strainer or colander over a bowl and carefully spoon the curds into the strainer. Allow the mascarpone to cool to room temperature, cover the strainer tightly with plastic wrap, and refrigerate for 24 hours to allow the cheese to finish draining and become firm. Store in the refrigerator in a tightly covered container. Use the mascarpone within 3-or-4 days.
