Creating the perfect Crispy Shrimp Tempura involves a few simple steps. Follow these instructions to achieve delicious results:

1. Prepare the Shrimp: Rinse the shrimp under cold water and pat them dry with paper towels.
2. Make the Batter: In a bowl, whisk together the all-purpose flour, cornstarch, baking powder, and salt. Gradually add the ice-cold water, stirring gently until just combined. Do not overmix; some lumps are okay.
3. Heat the Oil: In a deep skillet or pot, heat about 2 inches of vegetable oil over medium-high heat until it reaches 350°F (175°C).
4. Coat the Shrimp: Dip each shrimp into the batter, ensuring it is well-coated. Allow any excess batter to drip off.
5. Fry the Shrimp: Carefully place the battered shrimp into the hot oil, frying in batches to avoid overcrowding. Fry for about 2-3 minutes on each side or until golden brown.
6. Drain Excess Oil: Once cooked, remove the shrimp from the oil and place them on a plate lined with paper towels to absorb excess oil.
7. Repeat: Continue the process with the remaining shrimp, ensuring the oil temperature remains consistent.
8. Serve Immediately: For the best taste and texture, serve the Crispy Shrimp Tempura hot.
