Crispy Tempura Batter Recipe
Introduction
Tempura batter is a light, crispy coating perfect for vegetables and seafood. This basic recipe uses simple ingredients and cold sparkling water to create a delicate crunch every time.

Ingredients
- ½ cup cornstarch
- ¼ cup all-purpose flour
- ⅓ cup cold sparkling water
- Handful of crushed ice
- Pinch of fine sea salt
Instructions
- Step 1: In a bowl, combine the cornstarch, all-purpose flour, and a pinch of fine sea salt.
- Step 2: Gradually whisk in the cold sparkling water along with the crushed ice until the batter is just combined. Do not overmix; some lumps are fine.
- Step 3: Use the batter immediately to coat your choice of vegetables or seafood before frying for the best crispy texture.
Tips & Variations
- Keep the batter very cold to achieve maximum crispiness—using crushed ice helps maintain the temperature while preparing.
- For a gluten-free version, substitute the all-purpose flour with rice flour.
- Use sparkling water to add lightness and bubbles; avoid using plain water for a denser batter.
Storage
Tempura batter is best used fresh and shouldn’t be stored, as it will lose its fizz and texture. Prepare it just before frying to ensure the crispiest results.

FAQs
Can I use plain water instead of sparkling water?
Sparkling water provides bubbles that help keep the batter light and crispy. Using plain water results in a heavier, less crispy coating.
How do I know when to stop mixing the batter?
Stop mixing as soon as the dry ingredients are moistened with some lumps remaining. Overmixing can develop gluten and make the batter tough.
