Prep Time 5 minutes
Cook Time 10 minutes
Total Time 15 minutes

Ingredients

  • 340 g bittersweet chocolate or milk chocolate, if you prefer 12 oz
  • 400 g sour cream 1 and 2/3 cups or 14 oz

Instructions

  1. Melt the chocolate over a double boiler (over hot water). You could also use the microwave — do take the container out every 10 seconds and stir, until it has melted.

  2. Remove the chocolate from the heat, and while it is still warm add the sour cream. 

  3. Stir gently yet swiftly with a rubber/silicone spatula until the mixture is uniform in colour.

  4. If the bowl is still warm, transfer it to another bowl.
  5. Serving: You can use it immediately. If you wish to use it later, store it in an airtight container and when cool keep it in the fridge. When you’re ready to use it, heat in the microwave for a few seconds, and stir in gently, or place the bowl in a warm water bath.

Notes

Ensure that the chocolate mass in your chocolate is not over 53% (curiously, PBS video that showcases Rose baking, she mentions that the chocolate mass should not be over 64%), as anything more makes your sour cream ganache bitter. This recipe yields 4 and 3/4 cups of indulgent sour cream ganache (765 g or 1 lb 10 oz) — enough to fill and frost two 9-inch by 1 and 1/2-inch layers or three 9-inch by 1-inch layers. You could also use a beater to beat the sour cream and chocolate together — you just end up with a lighter coloured sour cream ganache, since there's more air beaten into it. With a spatula, it'll be thicker and darker.
