15-Minute Keto Strawberry Electrolyte Slushie
A refreshing, no-cook frozen beverage blending tart lemon with sweet strawberries, fortified with electrolytes and magnesium for hydration and muscle support. Perfect for post-workout recovery, hot days, or anyone following ketogenic eating. This version prioritizes bioavailability of supplements through proper mixing technique, setting it apart from standard smoothies by including potassium chloride and magnesium glycinate for balanced electrolyte replacement.
Ingredients
Instructions
- 1
Juice fresh lemons.
- 2
Dissolve magnesium supplement in small amount of water, let fizzing settle and water clear before using.
- 3
Add chilled water, lemon juice, sweetener, frozen strawberries, potassium chloride, sea salt, and ice to blender.
- 4
Blend until snow-like consistency forms.
- 5
Serve immediately.
Tips
Pre-dissolve magnesium supplement in water and let fizzing completely settle before blending for optimal absorption and smoother texture without cloudiness.
Use frozen strawberries directly from freezer for best slushie consistency; thawed berries will make drink watery and dilute electrolyte concentration.
For single servings, blend 1/2 cup water, 1 tbsp lemon juice, 1/2 tbsp sweetener, 3/4 cup frozen strawberries, pinch potassium chloride, pinch salt, 1 tbsp magnesium supplement, and 1.5 cups ice.
Good to Know
Consume immediately for best texture. Leftover unfrozen slushie keeps refrigerated up to 2 hours; ice will melt and separate from liquid.
Prepare ingredients separately: juice lemons and store covered refrigerated up to 2 days. Pre-portion dry ingredients (sweetener, potassium, salt, magnesium) in container up to 1 week. Freeze strawberries up to 3 months. Blend fresh when ready to serve.
Serve immediately in chilled glass. Pair with salty snack like nuts or cheese to enhance electrolyte benefit. Ideal post-workout or during hot weather for rehydration.
Common Mistakes
Do not skip pre-dissolving magnesium supplement to avoid cloudy texture and reduced bioavailability.
Do not use room-temperature water to avoid melting ice and creating weak, watered-down drink.
Do not over-blend to avoid creating liquid smoothie instead of slushy snow consistency.
Substitutions
FAQ
Can I make this without the magnesium supplement?
Yes, the slushie works without it for basic hydration and flavor. However, you lose the magnesium and Natural Calm's electrolyte benefit. If omitting, double the potassium chloride to 1 tsp and increase sea salt to 1/2 tsp for better electrolyte balance.
What if I don't have frozen strawberries?
Use fresh strawberries with additional ice cubes (increase to 4-5 cups) to achieve slushy texture. Add strawberries last and blend just until mixed to avoid over-processing. Texture will be less smooth and more chunky than frozen version.
How long can I keep a made slushie?
Consume within 15-20 minutes while frozen and textured. After 30 minutes at room temperature, it becomes liquid and separates. If refrigerated, it stays drinkable up to 2 hours but loses ideal slushy consistency as ice melts.
