Why it works: Wasabi and flour share more aroma than cooks usually use. They rank in the top 7% of all ingredient pairs, and 28 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe
Ingredients
Contains: egg, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
- For Batter
Directions
Prepare
Thinly slice the wasabi root.
Lightly beat the egg until the yolk is broken and starting to blend with the white.
Stir in the flour and the water until just combined; do not overmix the batter; there should be a few lumps.
Set the batter bowl in a larger bowl filled with ice cubes or crushed ice.
Fry
Heat about 12 cm (4") of vegetable oil in a deep heavy-based pan to a temperature of 180°C/350°F or until a cube of bread browns in 30 seconds.
Dip the thinly sliced wasabi root into the batter.
Carefully slip the battered wasabi root into the hot oil.
Fry the crisps five at a time for about 30 seconds until the batter is golden and very crisp.
Drain the crisps on kitchen paper.
Keep warm while frying the remaining crisps.
Serve
Serve at once with the Namida® Wasabi Mayonnaise.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Wasabi root
- Provides the sharp, pungent flavour that defines the crisps.
- Egg
- Adds richness and helps bind the batter to the wasabi slices.
- Plain flour
- Forms the structure of the batter that becomes crisp when fried.
- Cold water
- Keeps the batter thin and light, so it fries crisp rather than heavy.
The step that matters
Keep the batter cold and barely mixed. Cold batter and minimal stirring limit gluten development and keep the coating light and crisp. Overmixing makes it tough and greasy.
