You will need to use a whey protein powder. Most vegetarian and vegan protein powders do not fluff, so please don't try to fluff your pea protein, brown rice protein, or hemp protein.
If you do wish to use an unflavoured protein powder you can add xantham gum – ½ teaspoon per serving which will make your protein fluff stay fluffier longer and gain a thicker consistency. Using xanthan gum is optional.
Using other frozen vegetables or fruit
You can’t make Protein Fluff with fresh vegetables or fruit, it HAS to be frozen. If they are not frozen, you are in for a smoothie, not fluff.
What kind of vegetables can you use to make protein fluff? You can use frozen (cooked) cauliflower, frozen (cooked) sweet potato or butternut squash, or frozen carrots. You could also experiment with any other vegetable.
