Crema Agria (Homemade Sour Cream)

Since tomorrow is Cinco de Mayo, I decided to make some homemade sour cream to go with Tortilla Soup. Homemade sour cream is incredibly easy to make and only takes two ingredients. When made with heavy cream and fresh lime juice, it is called Crema Agria. When made with heavy cream and buttermilk, it is called Crema Espesa (or Creme Fraiche). The lime juice version does retain the taste of lime is tangier than the buttermilk version. Either version, however, is thinner and creamier than commercial sour cream, and has a fresher taste.

Crema Agria (or Crema Espesa)

2 c. heavy cream

1/4 c. fresh lime juice (or buttermilk)

1. Warm heavy cream on stove until the cream reaches 90  to 100 degrees F (or about body temperature). Do not overheat the cream.

2. Stir in lime juice (or buttermilk).

3. Pour mixture into a glass jar. Cover loosely. Let sit at room temperature for 8 to 12 hours or until thickened. Cover tightly. Refrigerate for at least 4 hours before using.
