How to Prepare the Perfect Pistachio Eclairs: Step-by-Step Guide

Let’s dive into the fun part actually making these pistachio eclairs! Start by preheating your oven to 375°F, as that’s the key temp for those perfect pastry shells. You’ll combine 1 cup water, ½ cup unsalted butter, 1 tablespoon sugar, and ¼ teaspoon salt in a saucepan and bring it to a boil, then stir in 1 cup all-purpose flour all at once.

Once the dough forms a ball, cool it slightly before beating in 4-5 large eggs one at a time until it’s smooth and shiny. Pipe the dough into strips and bake for 30-35 minutes until golden, then slit the shells to release steam for the last 5 minutes. While that’s happening, prepare the mousse by pulsing ¼ cup unsalted roasted pistachios, heating 1 cup milk with them, and steeping for an hour before straining.

For the mousse, bloom 1 teaspoon gelatin powder in water, mix it with the milk, and cook a custard with 2 egg yolks, 2 tablespoons sugar, and ¼ teaspoon salt to 180°F. Pour this over 150 grams chopped white chocolate, blend smooth, add 25 grams pistachio paste, and fold in whipped ¼ cup cold heavy whipping cream. Finally, for the glaze, melt 3 oz chopped white chocolate with 2 tablespoons heavy whipping cream. Check out this classic eclair recipe for even more inspiration on perfecting your technique.
