How We Test Recipes and Rate Blenders

Recipes

Each recipe is built on the same base ratio (about 1 cup liquid to 1½ cups frozen fruit) and adjusted until it pours thick but drinkable. We list exact amounts, the order to add ingredients and the fixes for common problems.

Nutrition

We calculate nutrition from USDA FoodData Central values for each ingredient at the amount listed, then divide by servings and round. Brand differences (especially protein powder, yogurt and plant milks) change the numbers, so treat them as estimates. This site is general information, not dietary advice.

Blender ratings

We rate blenders on four smoothie tasks:

  • Smoothness: fibrous greens, kale stems and berry seeds.
  • Frozen fruit & ice, whether it blends without constant stopping.
  • Ease: controls, presets, jar size, cleaning.
  • Value: price against performance and warranty.

Ratings combine manufacturer specs, warranty terms, current prices and published hands-on testing from independent reviewers and owners. We don’t accept payment or free products for placement.
