Step 1: Make the Candied Walnuts

1. 1. In a small saucepan, bring ½ cup water and ⅓ cup sugar to a boil over medium heat, stirring until the sugar dissolves.

1. Add the walnuts and let them simmer for 5 minutes, allowing them to soak in the sugar syrup.
2. Remove the walnuts with a slotted spoon and place them on a parchment-lined baking sheet to cool. They will harden and become crunchy as they dry.

Step 2: Prepare the Shrimp

1. Pat the shrimp dry with a paper towel. Season them with salt and white pepper.
2. In a small bowl, whisk the egg whites until frothy.
3. In a separate bowl, add the cornstarch.
4. Dip each shrimp into the egg whites, then coat them in cornstarch, shaking off excess.

Step 3: Fry the Shrimp

1. Heat ½ cup vegetable oil in a deep skillet or frying pan over medium-high heat.
2. Once the oil is hot (about 350°F/175°C), add the shrimp in batches, frying for 2-3 minutes per side until golden and crispy.
3. Transfer the fried shrimp to a paper towel-lined plate to drain excess oil.

Step 4: Make the Honey Mayo Sauce

1. In a small bowl, whisk together mayonnaise, honey, condensed milk, and lemon juice until smooth.

Step 5: Toss Everything Together

1. In a large mixing bowl, combine the crispy shrimp and honey mayo sauce. Toss gently to coat the shrimp evenly.
2. Add the candied walnuts and mix lightly.

Step 6: Garnish and Serve

1. Transfer to a serving dish and garnish with chopped green onions and sesame seeds, if desired.
2. Serve immediately with steamed jasmine rice or on its own as an appetizer.
