海老の天ぷらTempura shrimp
Cold batter, hot oil, and a fry that lasts ninety seconds. The shrimp is seasoned in the batter, not before; the crispness is the dish, and the only thing between the plate and a plate of greasy dough is the oil temperature and the length of your attention.
Technique notes
This is the frying article with the stakes turned up: the window between "lacy and crisp" and "soggy and greasy" is about ten seconds wide, and it exists entirely at oil temperature. The knife work is deceptively unforgiving too — a shrimp that is only half peeled, or one that went into wet batter dripping, is the difference between tempura and a fried snack. The rest of the recipe is doing less: a batter you barely mix, and a fry you barely touch.
Equipment
- Deep, straight-sided frypan or small pot, 1.5 L oil depth
- Instant-read or deep-fry thermometer (chopstick tests are a myth if you want to repeat this)
- Slotted spoon and wire rack, or a plate lined with paper towel
- Wide, shallow bowl for the batter
Ingredients
- 450 g large shrimp (about 10–12), tails on — peel and devein, leave the last shell segment and the tail for grip and for the "crack" in the batter
- 1 tbsp salt water, plus 1 g salt mixed in it — the shrimp gets seasoned through the thin outer dip, not by marinating (raw fish doesn't take a salt cure the way meat does in a short window; see the marinating article for why acid-and-salt on raw shrimp goes a different direction)
- 100 g plain flour (all-purpose)
- 150 ml cold water — ideally iced, or cold sparkling water; the colder the liquid, the less the batter cooks before it hits the oil, and the lazier the lace
- 0.5 g (a pinch) salt for the batter
- 500 ml neutral, high-smoke-point oil (rapeseed or sunflower) — the classic is tempura oil, oroshi; anything that stays out of the way works
- Serve: lemon wedges, and either grated daikon soaked in water (classic) or a thin tenzu-yu dip: 50 ml cold water, 15 g dashi stock, 5 g sugar, 10 ml mirin, 5 ml light soy
Method
- Peel the shrimp down to the last shell segment and the tail pin. Cut shallow, even slices along the outer curve of the flesh — 3–4 per piece — so each one uncurls and fries flat; they would coil up mid-fry and cook unevenly without it. Pick out the vein and the dark line along the belly, then pat every piece as dry as you can with a towel. The drying is not optional: water on the surface flashes to steam and knocks the oil temperature locally, which is the exact moment the batter goes soft.
- Mix the flour, salt, and cold water with a chopstick — or a fork — until just combined. Stir about 8–10 times, no more: you want lumps and a thin film, not a smooth batter. Smooth batter is over-mixed gluten; over-mixed gluten turns out chewy and thick, the opposite of the lace you're after. Set it aside; the lumps relax and the batter actually wants to rest a minute before it's right.
- Heat the oil to 175 °C / 350 °F. If you're testing without a thermometer, drop in a 1 cm cube of the batter — it should sizzle immediately and start turning pale gold within about 10 seconds, not slowly bubbling at the bottom. The oil is ready when it is ready; there is no "almost there" stage for this dish. While you wait, dip each shrimp lightly in the batter, lift it, and let it drain — dip and drain, not dip-and-hold — so the shell side comes out of the bowl with a thin shell, not a coat. (You will hold the shrimp by the tail and dip flesh-first; the tail and last segment stay bare.)
- Fry in two batches — six per batch — because they must not touch each other; touching shrimp cook each other and the oil temperature will dip. Lower them in gently at about a 45° angle, tail pointing up, keeping them 5 cm apart. Turn each once, after about 30–40 seconds, so the un-dipped tail side also crisps. Stop turning: more than two turns in a minute of frying means you're not letting it cook.
- Lift out when the flesh is just opal and the shell is a uniform pale gold — not brown; brown means it spent longer than it needed to in the oil. Drain over the rack or towel, and immediately put a lemon wedge over each to finish the seasoning. Serve within two minutes of coming out of the oil. This is the last instruction before the window closes.
Common failures
- Soaking in the plate. The oil was below 170 °C when the shrimp went in, or they were crowded together and it dropped. Greasy tempura is a temperature problem, not a batter problem. Next time: more oil, bigger pot, lower heat, longer heat-up; and fewer shrimp per batch even if it takes three rounds.
- Clumpy, doughy batter instead of lace. You mixed it until smooth, or the water was room temperature. Both give the batter time to set thick on the shrimp before the shell has crisped. The batter should pour off a chopstick in a thin ribbon, and the water should be cold enough to make your fingers feel it.
- Shrimp curl up mid-fry. They weren't cut along the outer curve in step 1. Even a shrimp cut flat will still coil as it cooks — the muscle contracts — and a curled piece cooks the outside of the curl before the inside is done. The shallow cuts along the outer curve are what let it lie flat for the whole fry.
- Soft after a few minutes, even if the oil was right. This is the one you can't fully fix — you serve tempura now, not later. It's a "make a batch, eat a batch" discipline, which is exactly why it's a party dish in the wrong context and a quiet weekend dish in the right one.
Variations & substitutions
- Vegetables in the same oil. Aubergine florets (1 cm slices), sweet potato sticks (0.5 cm square, blanched 2 minutes first), shingled okra or shimeji — the same thin dip and the same oil a notch hotter, 180 °C / 355 °F, because they have more water to lose, with a longer fry, 2–3 minutes.
- A touch of egg. Some kitchens add just the yolk of 1 egg to the batter for a slightly richer crumb. It's not traditional for the plain shrimp tempura, and it takes you a step away from the lace; use it on the vegetable, skip it on the shrimp.
- Smaller shrimp, or prawns. The method doesn't change, but the fry time drops to under a minute — start the turn sooner, and pull them at the first pale flush of colour. Big shrimp forgive a slow cook; small shrimp don't.
- No thermometer, no tenzu-yu. A plain sprinkle of flaked salt and a lemon wedge is still the dish. The tenzu-yu is the restaurant version of "a little sweet and a little salt" and can be skipped without the plate being worse off, provided the shrimp were dry and the oil was right.
What to serve with it
Warm steamed rice on the side, not underneath — the crispness is the point, and rice under the shrimp steams the bottom of the batter off within a minute. A cool green or a steamed vegetable, a cold beer, and the lemon on the plate. The rice can wait for the second round of the shrimp if the plate went down cold.
