Tempura (Crispy Fried Seafood and Vegetables)
Why this recipe works
- Delicate crispness: A loose batter made with plain flour, cornflour and egg fries quickly, creating a light shell rather than a heavy crust.
- Classic tempura handling: Keeping the batter cold and only briefly mixed limits gluten development, helping the coating stay fine, airy and crisp.
- Savoury dipping sauce: Dashi, soy sauce, mirin and ginger add umami, gentle sweetness and warmth without overwhelming the seafood or vegetables.

Timing notes
- Serve straight away: Tempura is at its best immediately after frying, before steam softens the coating.
- Prep before mixing the batter: Cut and dry the prawns and vegetables first, then make the batter just before frying for the lightest result.
Authenticity notes
- Pale golden is correct: Tempura is usually fried to a light golden finish; the aim is delicacy and crispness, not a dark, crunchy crust.
- Dashi-based dipping sauce: A soy, mirin and dashi sauce is a classic partner, adding savoury depth while keeping the fried pieces the focus.
Common mistakes
- Letting the oil temperature drift: Keep the oil close to 170°C (340°F); cooler oil can make the batter greasy, while hotter oil may brown the coating before the vegetables are tender.
- Frying too much at once: Work in small batches so the oil recovers quickly and the pieces fry cleanly rather than steaming together.
- Not checking the prawns: The prawns should be opaque all the way through with no grey centre, especially when serving children, older adults or other vulnerable groups.
Ingredient notes
- Dry ingredients matter: Pat the prawns and vegetables dry before coating so the batter clings evenly instead of sliding off.
- Slice dense vegetables thinly: Sweet potato needs thin rounds so it cooks through within the short frying time and stays tender inside.
- Dashi sets the tone: Dashi powder gives the dipping sauce its characteristic Japanese savoury base; adjust the sauce to taste if using a different dashi product.

Instructions
- Make the dipping sauce: warm the water in a small saucepan, whisk in the dashi powder, then stir in the soy sauce and mirin. Bring just to a gentle simmer, then take off the heat. Finely grate the ginger and stir it in, then set aside to cool.
- Prepare the tempura ingredients: pat the prawns dry, then make 3 to 4 shallow slashes along the belly side so they stay straight when fried. Cut the aubergine into thin wedges and slice the sweet potato into thin rounds; cut the broccoli into small florets. Keep everything as dry as possible so the batter clings well.
- Pour the vegetable oil into a large pot to a safe depth and heat to 170°C (340°F), using a thermometer to monitor. While the oil heats, set a sieve-strainer over a bowl for draining. Keep the heat steady so the tempura cooks quickly without browning too much.
- Make the batter: in a mixing bowl, whisk the egg with 180 ml of the water until just combined. Add the plain flour and cornflour and whisk very briefly, leaving a few small lumps; overmixing makes the batter heavy. The batter should be loose enough to coat but not thick like pancake batter.
- Fry in batches: dip the prawns and vegetables into the batter, let the excess drip off, then lower into the hot oil with tongs. Fry for 2 to 3 minutes for prawns and 3 to 4 minutes for vegetables, turning once, until pale golden and crisp. Lift out to the sieve-strainer to drain, then return the oil to temperature before the next batch.
Recipe notes
Tips
- Keep the batter cold and mix it minimally; a few lumps are good and help keep the coating light.
- Fry in small batches so the oil temperature stays steady and the tempura stays crisp rather than greasy.
- If serving vulnerable groups, make sure the prawns are cooked through: they should be opaque all the way through with no grey centres.
Substitutions
- Replace Aubergine with Courgette for a lighter, quicker-cooking vegetable.
- Replace Sweet potato with Butternut squash, sliced thinly, for a similar sweetness and texture.
- Replace Mirin with Dry sherry for a similar sweetness and aroma in the dipping sauce.
Storage
- Refrigerate up to 1 days
- Tempura is best eaten straight away. If you must store it, refrigerate the fried pieces and the dipping sauce separately; reheat the tempura on a baking tray in a 200°C (390°F) oven for 6 to 8 minutes until hot and crisp, and warm the sauce gently in a saucepan.
