Cauliflower tempura has an airy, crisp coating that shatters when you bite into it. Florets are dipped in an ice-cold batter and fried until light golden, then served with a soy, rice vinegar, honey and sesame dipping sauce.
The Secret Is Cold Batter
Keep the water in the fridge until you’re ready to mix, and stir the batter just until combined; lumps are good. The contrast between cold batter and hot oil creates the bubbly, lacy tempura crust. Make the batter right before frying, fry in small batches at 350°F, and let the oil come back to temperature between batches.
Kosher Notes
This tempura is pareve. Tempura is often made with shrimp, which isn’t kosher; cauliflower makes a satisfying alternative. Check the cauliflower for insects, as kashrut requires, and use soy sauce and sesame oil with a reliable hechsher.
Reheating
Tempura is best right away, but leftovers crisp up in a 400°F oven in 3 to 4 minutes.

Method
- Cut the cauliflower into uniform florets, about 1.5 inches in size. Toss with kosher salt and let sit for 10 minutes to draw out excess moisture.
- Pat the cauliflower completely dry with paper towels. This step is crucial for getting the batter to stick properly.
- Whisk together soy sauce, rice vinegar, honey, and sesame oil until the honey dissolves completely.
- Stir in the sliced scallion and set aside.
- Heat oil in a heavy-bottomed pot or deep fryer to 350°F. Use a thermometer to monitor temperature throughout cooking.
- Set up a wire rack over a baking sheet for draining the finished tempura.
- In a medium bowl, whisk together flour, cornstarch, baking powder, and salt.
- In a separate bowl, lightly beat the cold egg, then whisk in the ice water.
- Pour the wet ingredients into the dry ingredients and stir just until barely combined. The batter should be lumpy and not overmixed.
- Working in batches of 4-5 pieces, dip each cauliflower floret into the batter, letting excess drip off.
- Carefully lower into the hot oil and fry for 2-3 minutes until golden and crispy.
- Remove with a slotted spoon and transfer to the wire rack. Repeat with remaining cauliflower.
