Tempura
Tempura looks like it should be difficult—all that golden crispness, the way it stays light instead of greasy. It's actually the opposite. The simplest batter and the coldest ingredients do the work for you. What matters is paying attention to temperature and not letting the batter sit.
Prepare everything before you start frying
Tempura moves fast once you begin. Vegetables should be cut and dried, batter mixed at the last moment, oil at the right temperature. Cold batter goes into hot oil—that contrast is what makes it work.

What goes in.
- 1 cupall-purpose flour
- 1 cupice water
- 1egg yolk
- 1 tspsalt
- vegetable oilfor frying (about 2 quarts)
- 1 lbvegetables (mushrooms, bell peppers, zucchini, green beans, shiso leaves) or shrimp, cut into bite-sized pieces
Cold batter, hot oil, no resting
The batter must stay cold and go directly into 350°F oil. Overmixing develops gluten and makes it heavy. Lumps are fine—they stay on the surface and cook separately, adding texture. If the batter sits more than a few minutes, it warms up and loses its lift.
The method.
Set up your workspace
Line a wire rack with paper towels. Pat vegetables completely dry with a clean towel—any moisture prevents crispness. If using shrimp, devein and dry them too.
Heat the oil
Pour oil into your pot to a depth of 3 inches. Heat to 350°F, measured with a thermometer clipped to the side. This takes 10–15 minutes depending on your pot. Don't skip the thermometer—too cool and it absorbs oil; too hot and it burns outside before cooking inside.
Make the batter
In a shallow bowl, whisk together flour and salt. In another bowl, whisk the egg yolk with ice water until combined. Pour the wet ingredients into the dry flour and stir gently with chopsticks or a fork—don't use a whisk. Stop as soon as everything is moistened. The batter should look rough with visible lumps. If it's smooth, you've mixed too much.
Fry in batches
Working with 4–6 pieces at a time, dip each item in batter, let excess drip off for a second, and slide it into the oil. Don't crowd the pan—pieces need room to float and crisp evenly. Fry for 2–3 minutes until the batter turns light golden and any batter that falls to the bottom has cooked and floated back up.
Remove and drain
Use chopsticks or a slotted spoon to lift each piece from the oil and place it on the prepared rack. The residual heat continues cooking the inside for a few seconds after it leaves the pan. Don't let pieces sit in a pile or steam will make them soggy.
Serve immediately
Tempura is best eaten within minutes of frying, while the outside is still crisp. Arrange on a plate and serve with dipping sauce (equal parts soy sauce, dashi, and mirin, chilled, or just sea salt).
Other turns to take.
Kakiage (mixed vegetable tempura)
Shred or finely chop mixed vegetables (carrots, onions, mushrooms, green onions), toss them together, and drop spoonfuls into the oil instead of dipping individual pieces. You get a crispy fritter that's half vegetable, half batter.
Shrimp tempura
Peel and devein large shrimp but leave the tail on. Pat dry. Make small cuts on the underside to keep them from curling too much. Fry for 2–3 minutes until they turn pink and the batter is pale gold.
Tempura don (over rice)
Serve finished tempura over a bowl of warm rice and pour hot dashi broth (seasoned with soy, mirin, and sugar) over the top. The broth softens the tempura slightly but the contrast is intentional—some crispness, some sauce-soaked batter.
Tempura soba or udon
Lay cooked noodles in a bowl, top with 3–4 pieces of hot tempura, and pour hot broth over everything. The steam from the broth wilts the items slightly while they still hold their crispness underneath.
When it doesn't go to plan.
Use ice water, not cold water from the tap. The colder the batter, the faster the coating sets and the crispier it becomes.
If your oil temperature drops below 340°F, remove the pan from heat for a minute or two and let it recover. Frying too many pieces at once cools the oil too much.
Don't reuse batter—make a fresh batch if you're frying a second round. Old batter loses its lift.
Thin items (shiso leaves, thin cucumber slices) fry in 90 seconds; thicker items (mushroom caps, shrimp) take the full 2–3 minutes. Watch for the moment the surface turns pale gold, not dark.
If batter is clumping on your pieces, it's too warm or too wet. Make sure water is truly ice-cold and that you stopped mixing before everything was smooth.
The ones that keep coming up.
Why is my tempura greasy instead of crispy?
Two reasons: either your oil isn't hot enough (it absorbs into the batter instead of sealing it), or you're frying too many pieces at once and dropping the temperature. Use a thermometer and fry small batches.
Can I make the batter ahead of time?
No. The batter starts losing its lift as soon as you mix it. Mix it right before you start frying, and make a fresh batch if you take a long break.
What's the difference between tempura and other fried batters?
Tempura uses a higher ratio of water to flour and includes an egg yolk, which keeps the coating thin and delicate. The batter is barely mixed, which leaves it airy. Most other fried batters are thicker and more uniform.
Can I use a different oil?
Yes. Vegetable, canola, peanut, or light olive oil all work. Avoid extra-virgin olive or nut oils—they have strong flavors that overpower the vegetables. You want an oil that stays neutral.
Do I have to serve it with dipping sauce?
No, but it's traditional. A light dipping sauce (soy and dashi) lets you taste both the tempura and the flavor of what you're eating. Plain sea salt is also excellent and lets the vegetables shine.
