Place the pistachios in a heatproof bowl and cover with boiling water. Let stand for 10 minutes to soften the nuts and loosen the skins.
02 -
Drain the pistachios well. Rub them inside a clean kitchen towel to remove most of the loose skins. A few remaining skins are fine.
03 -
Transfer the pistachios to a food processor or high-speed blender. Pulse until they become fine, damp crumbs, scraping the sides as needed.

In a small saucepan over low heat, warm the milk, white chocolate, and sugar for 4-5 minutes, stirring often, until the chocolate melts and the mixture is smooth. Do not boil.
05 -
Pour the warm chocolate mixture over the ground pistachios. Add the oil, vanilla, and salt, then blend for 2-4 minutes until thick, glossy, and as smooth as your machine can make it.

If the cream is too thick to blend, add warm milk 1 teaspoon at a time. Spoon into a clean jar, cool, then refrigerate until slightly firmer before serving.
