pistachio cake

Heat oven: To 325 degrees F. Line the bottom and long sides of a loaf pan with a sling of parchment paper. Coat paper and exposed short sides of loaf pan with nonstick spray or butter. With a food processor: In the work bowl of your food processor, grind pistachios, sugar and salt together until as powdery as you can get them without it turning to paste. Cut butter into small chunks and blend with pistachio mixture. It’s going to be lumpy at first, and then balled for a minute, but keep running the machine until the mixture loosens up into a frosting-like consistency, i.e. smooth and shiny. Add eggs, one at time, blending briefly between each, scraping down sides as needed. Add milk, blend to combine. Add extracts and baking powder and blend to fully combine, scraping down workbowl. Add flour and pulse just until it disappears. Without a food processor: You’re going to want to start with 140 grams pistachio meal or flour and softened butter and can proceed as with a traditional cake. Beat butter and sugar until fluffy, then beat in eggs, one at a time. Beat in milk, then extracts until smooth. Beat in salt and baking powder until fully combined, scraping down bowl well. Add flour and mix just until it disappears.To bake: Scrape batter into prepared pan and spread top smooth. Bake for 60 to 70 minutes (see note up top by way of explanation/apology). Mine took 70, but it’s safest to check sooner. Look for a toothpick inserted into the center of the cake to come out clean and then, do a second check near the top. I find with loaf cakes that the undercooked batter likes to hover right below the top crust. It often takes 10 minutes extra (built into this baking time already) just for that to set for me.Let cake cool in pan on rack for 10 to 15 minutes, then run a knife around cake and transfer to cooling rack. Let cool completely.To make glaze (optional): Bring pistachios, sugar, zest, and juice to a simmer in a small saucepan; simmer for 2 to 3 minutes then pour over cooled cake. To serve: Cut into slices. Cake is great on the first day but even better on the second, as the ingredients settle. Keep at room temperature for several days, wrapped in foil, or longer in freezer.
