FAQs

Can I use coconut flour instead of almond flour?

Yes, but use ¼ cup coconut flour as it absorbs more liquid.

Why is my tempura not crispy?

Make sure the oil is hot enough (350°F/175°C) and don’t overcrowd the pan.

Can I make this dairy-free?

Yes! Replace whey protein with egg white protein or extra almond flour.

What’s the best oil for frying?

Avocado oil, coconut oil, or beef tallow work best for keto frying.

Can I use still water instead of sparkling water?

Sparkling water helps create a light, airy batter, so it’s recommended.

Is this tempura batter gluten-free?

Yes! It contains no wheat flour, making it perfect for gluten-free diets.

Can I bake this instead of frying?

Yes, but the texture won’t be as crispy. Bake at 400°F (200°C) for 15-20 minutes, flipping halfway.

What keto-friendly sauces go well with tempura?

Try spicy mayo, garlic aioli, sugar-free teriyaki, or low-carb soy sauce.

Absolutely! It works great for keto fish and chips.

How do I keep tempura crispy longer?

Drain on a wire rack instead of paper towels and serve immediately.
