Mascarpone Cheese
Ingredients
1 pint heavy cream
1/2 tsp tartaric acid
1/4 tsp confectioner's sugar
Directions
1 Fill the bottom of a double boiler with enough water to touch the top pan, but the top should fit neatly and not "float." Bring to a simmer.
2 Pour the cream into the top of a double boiler and place over simmering water.
3 Add the confectioner's sugar and whisk constantly.
4 When the cream is warm add the tartaric acid. Whisk over the heat until the cream reaches a temperature of 180 degrees.
5 Remove from heat and allow to cool, whisking occasionally.
6 Pour the mixture into a bowl through a thick cheesecloth, or line a fine metal strainer with a coffee filter.
7 Cover the bowel and refrigerator for at least 12 hours before use.
