Fried food you actually want to eat — even when you're not that hungry.

That's the strange thing about tempura. It's cooked in oil, but it leaves almost no heaviness behind. And it might be the only fried dish where vegetables get to be the star.

The Secret: Tempura Is Actually Steaming

"Tempura is really a steaming dish. The batter traps the moisture inside the ingredient. If you fry it too long, the water escapes and the flavor goes with it."

Kaa-chan heard a professional tempura chef say this on television once, and it was one of those moments where everything suddenly made sense. And apparently the science backs it up.

When tempura hits hot oil, the water in the batter vaporizes almost instantly — forming a crispy shell. Inside that shell, the ingredient's own moisture turns to steam and cooks the food from within, at high heat, all at once. The batter protects. The steam does the cooking. The oil never really gets in.

That's why tempura feels light. That's why it doesn't sit heavily. It's not absorbing oil — it's steaming itself from the inside out.

Tendon — How the Style Has Changed

Tempura over rice — tendon (天丼) — has its own history worth knowing.

In older Japanese households, the standard approach was to simmer the tempura briefly in tentsuyu sauce before laying it over the rice. A way to reheat it, and to let the sweet-savory flavor soak all the way into the batter. That was how it was done at Kaa-chan's home too.

Over time, the crispy-fresh style took over — tempura placed directly on the rice, sauce poured over the top at the last moment. The first time Kaa-chan saw that, the reaction was: "What an elegant way to eat." 😄

The old simmered style and the modern crispy style are both real Japanese food culture. Neither is wrong.

Kaa-chan's tip: For an affordable tendon in Japan, look for Tenya (天丼てんや). A national chain centered in Tokyo, serving freshly made tendon at prices that are genuinely reasonable. Takeout is available too — perfectly fine to bring back to the hotel.

Mom's Tempura, and the Counter That Changed Everything

Growing up, Kaa-chan's favorite dinner was freshly fried tempura straight from the kitchen. Sweet potato, fluffy and hot. Shrimp, springy and plump. And on nights when the family was having soba or udon, there was always kakiage — a mixed fritter packed with whatever was on hand.

Then, in Kaa-chan's 20s, a mentor from work took Kaa-chan to a tempura specialty restaurant with counter seating for the first time.

Each piece came out of the oil one at a time, placed directly on the plate, still crackling. The heat, the freshness, the precision — "This is unbelievably good."

The piece that stopped Kaa-chan completely: shiso (大葉) tempura. A single leaf. Battered and fried.

Who thinks to fry a leaf? There's barely anything there. 😄 But the texture — that delicate crunch — and the clean, herbal fragrance that came through the batter: it was a revelation. Tempura could be this refined.

Kaa-chan's mom, meanwhile, chopped shiso into small pieces and buried it in kakiage — "whatever's around, mix it together and fry it." That boldness is its own kind of genius.

Coat it in batter and it'll be delicious — shiso leaf, mixed fritter, whatever it is. There's something deeply Japanese about that approach: an enthusiastic curiosity about food, and an absolute refusal to let anything go uneaten and unenjoyed. Kaa-chan finds it charming every time. 😄

Mom's home kakiage and the counter chef's single shiso leaf — both are unforgettable in completely different ways.

What to Order — and How to Eat It

Common Tempura Ingredients

Vegetables: eggplant, kabocha pumpkin, sweet potato, lotus root, shiso, green pepper, green beans, kakiage (mixed fritter)

Seafood: shrimp, anago (sea eel), kisu (Japanese whiting), aji (horse mackerel), scallop, squid

Meat: kashiwa ten (かしわ天) — chicken thigh tempura, originally from Kyushu and Shikoku, now found across Japan. Pairs brilliantly with udon. Kaa-chan has been on a kashiwa ten phase lately. 😄

How to Eat It

Tentsuyu (天つゆ) + grated daikon — the classic pairing. Stir the daikon into the dipping sauce; it cuts through the oil and refreshes the palate between pieces.

Salt — lets the ingredient itself come through most directly. The higher-end the restaurant, the more likely they'll recommend salt. Sometimes it comes flavored with matcha or yuzu.

There's no single right answer. Kaa-chan prefers tentsuyu or salt. Kaa-chan's son eats everything with salt while it's still crispy. Kaa-chan's husband goes straight for the tentsuyu. Find what works for you.

If you get the chance to eat tempura in Japan, try paying attention to what's happening inside the batter — the steam, the moisture, the ingredient cooking in its own heat. It changes how it tastes.
