Have two ounces of fine, dried pistaches, using only the best quality ; put them into a pie-plate, place it in the oven to let the nuts get a light brown color, which will take about six minutes ; remove from the oven, lay the pistaches in a mortar with one ounce of granulated sugar, and pound slightly. Have a cream preparation exactly the same as for coffee ice-cream (No. 1273), suppressing the coffee. When cooked, add the pint of sweet cream and the pistache, then place it on the stove and heat well, stirring continually. Remove from the fire, cover the basin with a napkin, and let get thoroughly cool for thirty minutes. Add three drops of orange-flower water and five drops of spinach-green, mix the whole well for two minutes, then strain through a fine sieve into the freezer, and proceed to freeze and serve exactly the same as for vanilla ice-cream (No. 1271).
