Japan — ebi tempura as the signature tempura ingredient; Tenjo (Edo period) records note shrimp as primary tempura protein
Ebi (shrimp) tempura is Japan's signature tempura — and its proper preparation reveals technique sophistication. The defining feature: straight, elongated shrimp with no curl — achieved by making 4-5 shallow cross-cuts on the belly side and then gently pressing flat to break the connective tissue that causes curling during frying. The resulting straight shrimp is then coated in the lightest possible batter (ice-cold, minimally mixed, lumps acceptable) and fried at 175-180°C until the batter is just barely set — 90 seconds. Premium ebi tempura uses kuruma-ebi (tiger prawn) or botan-ebi when available; standard is large black tiger shrimp.
Sweet fresh shrimp through a barely-there crispy batter — the coating should enhance, never mask, the shrimp's natural sweetness
{"Cross-cut technique: 4-5 shallow diagonal cuts on belly side, gently press flat — breaks curl muscle","Devein carefully: maintain shrimp structure; puncture or rough handling weakens the texture","Tail treatment: leave tail shell on; cut tip and squeeze out moisture — prevents oil explosion","Batter: ice cold water + egg + flour, mix 5-6 times only — lumps are essential for light texture","Oil temperature: 175-180°C for shrimp — precise timing 90 seconds total","Drain immediately: vertical stand on rack for 30 seconds — excess oil drains from tail down"}
{"Two-stage batter: dip in dry flour first (light coat), then tempura batter — improves adhesion","Kuruma-ebi selection: large live prawns are the premium — natural sweetness expresses through thin batter","Progressive frying: start at 175°C, raise to 185°C last 20 seconds — final crisp without overcooking","Tempura tane (ingredients) order: delicate vegetables first at lower temp, protein last at higher","Second use of batter: batter deteriorates over 20 minutes — make fresh batches rather than holding"}
{"Not breaking curl tissue — shrimp curls in oil; cross-cuts must penetrate the connective tissue","Over-mixing batter — gluten activates, creates dense coating rather than light crispy shell","Warm batter water — warm water activates gluten; batter must be ice-cold throughout frying","Too-thick coating — excess batter creates heavy, doughy result; thin coating is the professional standard"}
