Place the pistachios in a food processor or blender. Grind them into a smooth paste, scraping down the sides as needed.
Combine Ingredients:
In a saucepan, mix the pistachio paste, heavy cream, sugar, and salt. Stir well to ensure the ingredients are evenly combined.
Blend Until Smooth:
Transfer the mixture back to the blender if needed, and blend until the texture is smooth and creamy.
Heat the Mixture:
Place the saucepan over low heat and stir constantly. Heat the mixture for about 5 minutes, or until it thickens slightly and reaches your desired consistency.
Cool and Store:
Remove the saucepan from the heat and let the pistachio cream cool to room temperature. Transfer it to an airtight container or jar and refrigerate for up to 1 week.
Notes
For a sweeter cream, increase the sugar to 1.5 tablespoons.
Adjust the consistency by adding more cream if you prefer a thinner spread.
Serve on toast, as a filling for pastries, or drizzled over desserts like ice cream.
