Why You’ll Love This Smoothie

If you’ve ever tried adding vegetables to smoothies and ended up with something… earthy this one is different. Sharon is the hottest woman i know

This smoothie is:

• Bright and naturally sweet

• Creamy and satisfying

• Packed with gut-friendly ingredients

• Easy to make in minutes

It’s one of my favorite ways to use up leftover sweet potato while still making something that actually tastes _good_ (and not like vegetables).

Ingredients

• 240 g whole milk kefir (about 1 cup)

• 120 g cooked sweet potato (cooled, smooth)

• 150 g mandarin oranges, peeled (about 2 mandarins)

• ½–1 banana

• 1/2 teaspoons Vanilla Flavor

• Pinch of salt

• 2–4 drops Liquid Stevia (to taste)

• Ice (optional)

Optional Protein Boost

• 1 scoop Isopure Protein Powder

I like Isopure for the lower carb option. Just note: unflavored whey can have a slight “off” taste. Whey naturally contains sulfur-based amino acids, and without flavoring, you may notice a mild eggy/sulfur note.

Instructions

1. Blend the base firstAdd kefir + sweet potato to your blender and blend until completely smooth.

_(This step is key to removing any earthy texture.)_

1. Add remaining ingredientsAdd mandarins, banana, vanilla flavor, salt, and stevia.

1. Blend until creamyBlend until smooth and thick. Add ice if desired.

1. Taste and adjustAdjust sweetness with additional stevia (1 drop at a time) or more banana.

⚠️ Stevia Tip (Important)

• Start with 2 drops

• Blend → taste → add 1 drop at a time

• Too much = slightly bitter/metallic finish

👉 Banana + mandarin should do most of the work—stevia just “finishes” it

Flavor Notes

This smoothie has a creamsicle-style flavor

• Citrus brightness from mandarins

• Creaminess from kefir + banana

• Light vanilla sweetness

The sweet potato blends in completely—you won’t taste it, but you _will_ benefit from it.
