Heat the oil to 350 to 365 degrees. Wash the summer squash, cut the ends off and slice it into pieces about 1-inch by 3-inches in length. This shape cooks more evenly than round circles. Dip the pieces in the milk and then dredge them in the flour. Place the pieces carefully into the hot oil. Cook for about 5-7 minutes depending on how many pieces you are frying. They should be golden brown when cooked thoroughly. Use a slotted spoon to remove the pieces and place them on a cooling rack with a paper towel between the cookie sheet and the cooling rack. Sprinkle with salt and pepper to taste. Serve with your favorite Ranch Dressing as a dip.
