Pistachio Ganache
This pistachio ganache filling needs about 2 hours to set, so I recommend making it before whatever dessert you want to fill it with! It can also be made up to a week in advance. I usually make it the night before.
Pour 180g of heavy cream and 60g of shelled and peeled pistachios into a small saucepan. Heat the cream over medium heat until it just starts to simmer/bubble.
IMMERSION BLENDER INSTRUCTIONS (preferred): Pour the pistachios and cream into a medium-sized bowl. Add 240g of white chocolate into the bowl and make sure all the white chocolate is submerged beneath the cream. Let the mixture sit for a couple of minutes, then use an immersion blender to combine the ingredients until the pistachios are broken down into small pieces.
FOOD PROCESSOR INSTRUCTIONS: Remove from heat and pour the mixture into a food processor or blender. Blend until combined and smooth. Pour the mixture into a medium bowl. Add 240g of white chocolate to the blended pistachio/cream mixture. Make sure all the white chocolate is submerged beneath the cream. Let the mixture sit for a couple of minutes, then mix it with a spoon or spatula until combined and smooth.
If desired, add a small drop of green gel food coloring and a sprinkle of fine salt. This ganache is naturally a greenish-yellow color, but I usually add a bit of coloring to give it a brighter green color.
Press a piece of plastic wrap flush against the ganache and place the bowl in the fridge to chill for about 2 hours. If you want to accelerate the cooling process, stir the ganache in 15-minute intervals.
When you're ready to use this ganache, place it in a piping bag fitted with a large round piping tip. It should be thick enough to scoop into the piping bag and hold its shape. If you made it in advance and it's really firm coming out of the fridge, let it sit at room temperature for about 30 minutes before using it. I love to fill my macarons and vanilla cupcakes with this ganache, but the sky is the limit. Fill your favorite desserts and enjoy!
