When I think of perfect tempura, I don’t picture heavy, soggy batter. It’s about that delicate, almost whisper-thin coating that lets the shrimp’s natural sweetness shine through. Achieving that lightness takes some practice, but once you get it, it’s like biting into a cloud of crispy goodness.
This recipe is a little obsession of mine. I’ve messed around with different batters—more flour, less, egg, sparkling water—and found that the best tempura is all about balance. It’s humble, almost minimalist, but when done right, it’s downright addictive. No heavy greasiness, just pure, crackling crunch with every bite.
Focusing on the overlooked importance of a light, crisp batter that highlights the prawn’s natural sweetness, rather than overpowering it with heavy coatings.
The overlooked art of crispy batter
- Crisping up that first prawn always makes me smile—there’s something satisfying about hearing that crackle.
- I remember the chaos of my first attempt—oil splattering everywhere—but that light batter made it worth it.
- Nothing beats the nostalgic smell of frying tempura after a long day, pulling me right back to childhood kitchens.
- Getting the batter just right feels like a small victory—it’s delicate, almost like a culinary secret I learned to keep.
- Sharing these crispy prawns with friends, watching their eyes light up, reminds me why I love cooking from scratch.
The story behind this recipe
- I first stumbled upon tempura during a trip to Japan, watched a street vendor expertly flick batter onto hot oil, and thought, ‘That’s it, I need to learn this art.’ The lightness of their batter was almost magical, like it couldn’t possibly hold the prawn, yet it did—delicately wrapping it in crispness.
- Since then, I’ve been obsessed with recreating that perfect balance. Every batch is an experiment—adjusting the water, the flour, the oil temperature—hoping to capture that fleeting moment when everything comes together. It’s not just about frying; it’s about chasing that whisper-thin, crackly coating that sings with every bite.

Historical tidbits about tempura
- Tempura originated in Japan in the 16th century, influenced by Portuguese fritter techniques introduced by missionaries and merchants.
- The word ‘tempura’ likely derives from the Latin ‘temperare,’ meaning to mix or temper, referencing the batter’s delicate balance.
- Early tempura was a luxury dish, reserved for special occasions, due to the costly ingredients and precise technique required.
- Traditional tempura batter is kept cold and lightly mixed to create that signature airy, crisp coating that’s unlike thick batters.
Key ingredients at a glance
- Prawns: I prefer medium-sized, fresh prawns with a firm bite—look for a slight translucence and a sweet scent; you can swap for scallops if you want a different seafood note.
- Tempura Flour: I use a blend of all-purpose and rice flour for that extra crispness—if unavailable, just stick with plain all-purpose, but expect a slightly denser batter.
- Ice Cold Water: It’s the secret to that light batter—use ice cubes or very cold water, and don’t overmix; room temperature water will make the batter gummy.
- Egg: Just one, lightly beaten—adds a touch of richness but keep it minimal so the batter stays delicate; omit if you’re gluten-free or want a vegan version (try sparkling water instead).
- Oil for Frying: Neutral oil like vegetable or canola—heat to around 180°C/356°F; if you notice smoking, lower the heat slightly or swap for peanut oil for a nuttier flavor.
- Salt & Seasonings: Keep it simple—just a pinch of salt in the batter and a squeeze of lemon at the end; skip if you prefer cleaner, purer prawn flavor.
Spotlight on key ingredients
Prawns:
- I look for medium-sized, fresh prawns with a firm, slightly translucent flesh and a sweet aroma; they hold together well and fry beautifully.
- Prawns tend to curl slightly when they hit hot oil, creating that classic tempura shape—if they stay straight, they might need a bit more time or heat adjustment.
Tempura Flour:
- I prefer a mix of rice and all-purpose flour for extra crunch—if you only have plain flour, your batter will still work but might be a tad denser.
- The flour’s texture influences how the batter crisps up—use fresh, sifted flour for maximum lightness and avoid lumps for a smoother coating.

Step-by-step guide to prawn tempura
- Equipment & Tools: Prepare a deep-fry thermometer to monitor oil temperature, a slotted spoon for frying, a mixing bowl for batter, and paper towels for draining excess oil.
- Peel and devein the prawns, leaving the tails intact for easier handling and presentation. Keep them cold in the fridge until ready.
- In a bowl, combine 1 cup tempura flour with 1/4 cup rice flour. Whisk in 1 beaten egg and about 1 cup ice-cold water until just combined. The batter should be lumpy and cold.
- Heat oil in a deep pan or wok to 180°C/356°F. Use the thermometer to keep precise control. The oil should shimmer but not smoke.
- Dip each prawn into the batter, allowing excess to drip off. Gently lower into hot oil, one or two at a time, to avoid splatters.
- Fry for 2–3 minutes, turning occasionally. Look for a golden, crackly crust. The prawns should be opaque and firm when tested with a skewer.
- Remove prawns with a slotted spoon and drain on paper towels. Check for a light, airy batter with a crisp bite. If soggy, the oil was too cool or batter was too thick.
- Rest & Plate: Serve immediately on a warm plate, garnished with lemon wedges or a dipping sauce. Keep crispy by serving within 5 minutes of frying.
Serve immediately while crispy. Rest prawns on a paper towel briefly if needed—avoid stacking to keep their crunch. Garnish with lemon and dip as desired.
How to Know It’s Done
- The batter should cling lightly, not heavy or greasy.
- Oil temperature remains steady around 180°C/356°F for even crispness.
- Prawns turn opaque and develop a golden, crackly crust.

Method
- Prepare your frying setup by heating vegetable oil in a wok or deep pan to 180°C/356°F, using a deep-fry thermometer to monitor the temperature.
- Peel and devein the prawns, keeping their tails intact for easy handling and presentation. Chill them in the fridge until ready to fry.
- In a mixing bowl, combine the tempura flour and rice flour (if using). Whisk in the lightly beaten egg and then gently add the ice-cold water, stirring just until the ingredients come together with a lumpy, slightly runny batter. Avoid overmixing to keep it light and airy.
- Once the oil reaches the correct temperature, dip each prawn into the batter, allowing any excess to drip off gently.
- Carefully lower the battered prawns into the hot oil using a slotted spoon, frying a few at a time to prevent crowding. Listen for a lively sizzle as they hit the oil.
- Fry the prawns for about 2–3 minutes, turning occasionally, until the batter is a light golden brown and crispy. The prawns should be opaque and firm when tested with a skewer.
- Use a slotted spoon to remove the prawns from the oil, then drain on paper towels to absorb excess oil and keep them crispy.
- Arrange the tempura prawns on a serving plate. Serve immediately with lemon wedges or your favorite dipping sauce for maximum crunch and flavor.
Essential tips for perfect tempura
- Bolded Mini-Head: Use ice-cold water → Keeps batter light and airy, preventing it from becoming gloopy.
- Bolded Mini-Head: Don’t overmix the batter → Lumps are fine; overmixing develops gluten and makes it heavy.
- Bolded Mini-Head: Test oil temperature → Drop a small bit of batter; if it sizzles immediately and rises, you’re ready.
- Bolded Mini-Head: Fry in small batches → Avoid overcrowding; temperature drops and batter softens, resulting in soggy tempura.
- Bolded Mini-Head: Maintain steady heat → Keep oil at 180°C/356°F for that perfect crackly crunch, adjusting as needed.
- Bolded Mini-Head: Drain on paper towels → Keeps prawns crispy by removing excess oil immediately after frying.
- Bolded Mini-Head: Serve straight away → Best texture and flavor; tempura cools quickly and loses crunch if left sitting.
Common tempura mistakes and how to fix them
- FORGOT to keep oil temperature steady → Use a thermometer to maintain 180°C/356°F.
- DUMPED batter into hot oil → Dip prawns gently to avoid splatters and soggy coating.
- OVER-TORCHED oil → Lower heat immediately if oil smokes or turns dark.
- FAILED to drain properly → Place fried prawns on paper towels to remove excess oil.
Quick Fixes for Crispy Perfection
- When oil smokes, splash a bit of cold water to cool and calm the heat.
- If batter clumps, patch with a gentle whisk or fold in a splash of cold water.
- Splash hot oil when batter hits for a crackling sound—if not, check oil temperature.
- DUMPED batter too thick? Thin it with a little ice-cold water for better coating.
- When prawns stick together, quickly shield with a slotted spoon and gently separate.
Prep, store, and reheat tips
- Peel and devein the prawns ahead of time; keep them chilled in the fridge for up to a day to maintain freshness and firm texture.
- Prepare the batter just before frying; if needed, cover and refrigerate for up to 30 minutes, but avoid made-ahead batter for best crispness.
- Fried tempura can be stored in an airtight container in the fridge for up to 2 hours; reheat in a hot oven (around 200°C/392°F) for 5–8 minutes until crisp.
- Avoid freezing cooked tempura, as it loses its delicate crunch and becomes soggy upon thawing; best enjoyed fresh.
- Reheated tempura may not be as crispy; for best results, reheat in the oven rather than the microwave to preserve some crunch and warmth.
