Tempura

Taste and texture

Tempura coats seafood or vegetables in a light flour batter and deep-fries them. Unlike breadcrumb-coated foods, its surface has no bread flakes; the batter cooks into a thin, irregular layer. Fish, mushrooms, roots and leafy vegetables can join shrimp in an assortment.

Flour and cold water form the basic batter, often with egg. Kikkoman uses cake flour and advises minimal mixing, while Just One Cookbook gives an all-purpose-flour example. Despite flour differences, both aim for a lightly combined batter rather than kneading it like elastic bread dough.

Overmixing develops stickiness that makes a crisp coating harder to achieve. That is why small flour lumps can remain and the batter is prepared just before frying. As the thin coating cooks in hot oil, the ingredient inside cooks while retaining moisture.

Thickness and preparation matter as much as the batter. Firm kabocha and sweet potato are sliced thinly; eggplant can be slit and fanned out, and tough shiitake stems removed. Different sizes and shapes help the interior cook before the crust is finished.

Shrimp can be peeled, deveined and given shallow cuts on the underside before being straightened. Long, straight shrimp tempura reflects this preparation rather than naturally emerging from the fryer that way. Drying ingredients and dusting them lightly with flour helps the batter adhere.

Mixtures also vary. Tim Anderson's vegetable tempura published by JNTO combines flour, cornstarch and sparkling water without egg. Small loose ingredients such as corn kernels can be gathered in batter and fried as kakiage, forming a fritter instead of individually coated pieces.

The pale coating breaks delicately, while the ingredients retain different textures: shrimp is springy, white fish separates into flakes, and sweet potato or kabocha is fluffy and sweet. The pleasure comes from tasting each ingredient beneath the crisp shell.

Eggplant and mushrooms become moist and tender inside. Lotus root retains a firmer bite around its perforated cross-section, while thin shiso leaves contribute fragrance and a light crunch. The vegetable's structure and moisture matter even when the batter is identical.

Adding too many pieces lowers the oil temperature and changes the crust. The recipes examined advise frying in batches and removing loose crumbs. Draining fried pieces on a rack also matters: retained moisture and excess oil weaken the crispness.

Tentsuyu combines dashi with soy sauce and mirin. This light, savoury dip soaks into the coating, adding saltiness and gentle sweetness. Grated daikon brings moisture and ginger adds sharpness. Dipping a portion briefly rather than soaking the whole piece preserves both crisp and softened areas.

Salt keeps the coating dry and lets the ingredient and crust taste more directly. Tempura served over rice as tendon, or in udon or soba broth, absorbs liquid where it touches the sauce or soup. The same fried item therefore changes texture differently as a separate dish or a rice or noodle topping.

How to order it in Korea

1. Look for “tempura” on the menu and check whether it is an assortment of seafood and vegetables or a single ingredient.
2. Ask whether it can come over soba, udon or rice, which turns it into a full meal.
