🥗 Ingredients
The Crab
- 4 pieces Prime Soft Shell Crabs (cleaned, patted very dry)
- 1/4 cup Cake Flour (for dredging)
Tempura Batter
- 1 cup Cake Flour (sifted and chilled)
- 1 Egg Yolk (large, cold)
- 1 cup Sparkling Water (ice-cold)
- 2-3 pieces Ice Cubes (to keep batter chilled)
Tentsuyu Dipping Sauce
- 3/4 cup Dashi Stock (kombu and bonito based)
- 3 tablespoons Mirin (sweet rice wine)
- 3 tablespoons Soy Sauce (Japanese light or dark)
- 2 tablespoons Daikon Radish (finely grated and drained)
- 1 teaspoon Fresh Ginger (finely grated)
Frying & Garnish
- 1 quart Neutral Oil (Rice bran, grapeseed, or canola)
- 1 tablespoon Toasted Sesame Oil (added to frying oil for aroma)
- 1 Lemon (cut into wedges)
- 1 pinch Sea Salt (Maldon or fine sea salt)
👨🍳 Instructions
-
1
Prepare the Tentsuyu sauce by combining dashi, mirin, and soy sauce in a small saucepan. Bring to a simmer over medium heat, then remove immediately and let it cool to room temperature.
-
2
Ensure the soft shell crabs are thoroughly cleaned (eyes, mouth, gills, and tail flap removed). Use paper towels to pat them extremely dry; moisture is the enemy of a crisp crust.
-
3
Fill a heavy-bottomed pot or wok with 2-3 inches of neutral oil. Add the tablespoon of toasted sesame oil for that authentic nutty aroma. Heat to 340°F (170°C).
-
4
While the oil heats, prepare the 'Daikon-Oroshi'. Grate the daikon and ginger. Squeeze the daikon gently to remove excess bitter liquid and set aside in small mounds.
-
5
Prepare the batter just before frying. In a medium bowl, lightly whisk the cold egg yolk and ice-cold sparkling water. Do not over-mix; bubbles are good.
-
6
Sift the chilled cake flour over the water-egg mixture. Use chopsticks to 'stab' and fold the flour in. Stop while there are still lumps visible—over-mixing develops gluten and makes the batter chewy instead of crispy.
-
7
Lightly dust each crab with the 1/4 cup of dry cake flour, shaking off every bit of excess. This acts as a primer for the wet batter to adhere.
-
8
Dip one crab into the cold batter, ensuring all nooks and crannies of the legs are coated, then carefully slide it into the hot oil.
-
9
Fry only 1 or 2 crabs at a time to maintain oil temperature. Use a spoon to drizzle a little extra batter over the legs while frying to create 'tenkasu' (crispy bits) that stick to the crab.
-
10
Fry for 2-3 minutes per side until the crab turns a vibrant orange-red and the batter is a pale, golden straw color.
-
11
Remove the crab and drain on a wire cooling rack (not paper towels) to allow air to circulate and prevent sogginess.
-
12
Skim any loose bits of batter from the oil between batches to prevent them from burning and tainting the flavor.
-
13
Serve immediately while piping hot. Place the crab on a plate with a lemon wedge, a mound of grated daikon/ginger, and a small bowl of the prepared dipping sauce.
💡 Chef's Tips
Always use cake flour rather than all-purpose; its lower protein content ensures a delicate crunch. Keep your batter ingredients ice-cold; the temperature shock between the cold batter and hot oil creates the signature airy texture. Do not over-mix the batter—lumps are your friend and prevent the coating from becoming bread-like. Use a thermometer to monitor your oil; if it drops too low, the crab will absorb oil and become greasy. If you can't find sparkling water, use very cold club soda or even a light Japanese lager for extra lift.
🍽️ Serving Suggestions
Pair with a chilled Junmai Ginjo Sake to complement the delicate sweetness of the crab. Serve alongside a simple Sunomono (Japanese cucumber salad) to provide a refreshing acid hit. A side of steamed short-grain white rice makes this a complete, satisfying meal. For a modern twist, provide a small dish of Matcha Sea Salt for dipping instead of the liquid sauce. Enjoy with a glass of dry Riesling or a crisp Sauvignon Blanc to cut through the richness of the fry.
