Mixed Fried Vegetables (Fritto Misto di Verdura)
This Italian favorite is an assortment of bite-size pieces of vegetables or other foods that are dipped in batter and deep-fried. The crispy morsels make an inviting appetizer,
Ingredients (Serves 6)
1/4 pound green beans, ends snapped off
1/2 broccoli, cut into thin spears 
6 scallions, root ends and green tops removed
2 zucchini, cut into 1/2-inch thick rounds
2 summer squash, cut into 1/2-inch thick rounds
1 green bell pepper, cored and cut into 1/2-inch thick strips
3 lemons, cut into wedges
1 cup cornstarch + 1 cup all-purpose flour
1 teaspoon salt
Vegetable oil, for frying
For the Lemon Mayonnaise
1/2 cup mayonnaise
 tablespoons fresh lemon juice
Preparation
For the fritto misto: Mix the flour, corn starch, and salt and pepper. 1. In a large heavy-bottomed saucepan, pour enough oil to fill the pan about 1/3 of the way. Heat over medium heat until a deep-frying thermometer inserted in the oil reaches 375 degrees F. (If you don't have a thermometer a cube of bread will brown in about 1 minute.)
2. Dredge the prepared vegetables in the flour mix. Fry the dredged ingredients for 2 to 3 minutes until lightly browned. Drain on paper towels.
For the lemon mayonnaise: In a small bowl, whisk the mayonnaise and lemon juice together until smooth. Pour into a small dipping or serving bowl. Serve the fritto misto with the lemon mayonnaise.
