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.
