Suyin's Shrimp Toast

Heat oil in a deep-fryer or large saucepan to 350 degrees F (175 degrees C). Lay bread slices on a tray.

Combine egg, celery, parsley, soy sauce, rice vinegar, cornstarch, salt, sesame oil, garlic powder, baking powder, black pepper, five-spice powder, and red pepper flakes in a bowl. Mix well.

Place shrimp, water chestnuts, green onions, garlic, and ginger in a food processor. Pulse into a chunky paste. Stir into the egg mixture until combined.

Place a generous dollop of the shrimp paste on each piece of bread; spread evenly towards the crusts using the back of a spoon. Sprinkle sesame seeds on top, pressing them into the paste. Cut each bread slice into 2 to 4 triangles.

Fry bread slices, paste side-down, in the preheated oil, until edges are golden brown, about 2 minutes. Turn bread over and fry until other side is crisp, about 1 minute. Transfer to a paper towel-lined tray to drain. Serve with sweet chili sauce.
