Ingredients Method Notes

Ingredients
  

  • 1 package 3.4 oz / 96g instant pistachio pudding mix (dry)
  • 1 can 20 oz / 567g crushed pineapple (do not drain — keep all the juice)
  • 2 cups small-curd cottage cheese full-fat or low-fat
  • 1 container 8 oz / 226g frozen whipped topping (like Cool Whip, thawed)
  • 2 cups miniature marshmallows
  • ½ cup chopped pistachios or pecans
  • Garnish Optional: Maraschino cherries and extra chopped nuts

Method
 

  1. 1.Dissolve and Thicken :2 min.
  2. Empty the dry pistachio pudding mix into a large mixing bowl. Pour in the entire undrained can of crushed pineapple, making sure to scrape out all the sweet pineapple juice. Whisk or stir vigorously for 1 to 2 minutes until the dry pudding powder is completely dissolved into the juice and the mixture begins to visibly thicken and turn a lovely green.
  3. 2.Blend in Cottage Cheese :1 min.
  4. Add the 2 cups of small-curd cottage cheese directly to the thickened green pudding base. Stir thoroughly until the cottage cheese is evenly distributed and fully coated by the pistachio mixture.
  5. 3.Fold in Whipped Topping :2 min.
  6. Spoon the thawed whipped topping into the bowl. Using a rubber spatula, gently fold the whipped topping into the pudding base. Use a circular motion, cutting down through the center and sweeping up the sides of the bowl, until you have a light, uniform, pastel-green color. Avoid stirring vigorously so you don't deflate the air.
  7. 4.Incorporate the Mix-Ins :1 min.
  8. Add the 2 cups of mini marshmallows and ½ cup of chopped pistachios (or pecans) to the bowl. Carefully fold them in just until they are evenly scattered throughout the fluffy salad.
  9. 5.Chill to Firm Up :2 hours.
  10. Cover the mixing bowl tightly with plastic wrap or a lid. Place it in the refrigerator to chill for at least 2 hours. During this time, the instant pudding will set firmly, the marshmallows will soften into pillowy clouds, and the flavors will meld.
  11. 6.Garnish and Serve :1 min.
  12. Give the salad a very gentle fold just before serving. Transfer to a serving dish and top with a sprinkle of extra chopped nuts and a few bright red maraschino cherries for a beautiful, classic color contrast.

Notes

  • Juice is Crucial: Do not drain the pineapple! The instant pudding mix relies entirely on the canned pineapple juice to hydrate, dissolve, and set.
  • The Nut Choice: Pistachios add an extra punch of pistachio flavor and a beautiful green hue, but chopped pecans or walnuts are also traditional and add a lovely buttery crunch.
  • Texture Timing: While it needs at least 2 hours to set, this salad tastes even better the next day once the marshmallows have fully softened into the cream. You can easily make this the night before your gathering!
