I’ve been making this cauliflower tempura for years now, and it’s become my go-to when I want something that hits all those crispy, satisfying notes without compromising on kashrut. The florets get this incredible light, airy coating that shatters when you bite into it, revealing tender cauliflower inside.
The technique here is all about the batter temperature and timing. Cold water is essential – I actually keep mine in the fridge until I’m ready to mix. The contrast between the cold batter and hot oil creates those signature tempura bubbles that make the coating so incredibly light. Don’t overmix either. A few lumps in the batter are actually what you want.
Getting Perfect Tempura Batter Every Time
What makes this version work so well is how the cauliflower’s natural sweetness plays against the crispy coating. I cut the florets into bite-sized pieces, about the size of large shrimp, which helps them cook evenly and makes them perfect for dipping. The key is getting your oil to exactly 350°F and maintaining that temperature throughout cooking.
Why Cauliflower Works So Well for This Technique
This makes an excellent appetizer for Shabbat dinner or holiday meals, especially when you want something a little different from the usual fare. I like serving it with a simple ponzu-style dipping sauce made with soy sauce, rice vinegar, and a touch of honey. It also works beautifully as part of a larger spread with other Japanese-inspired dishes.

Ingredients
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.
