Tempura batter is light, lacy, and ultra crispy. It is ideal for deep frying vegetables and seafood.
When I'm frying chicken, I prefer to dredge it in flour and shallow fry it rather than battering and deep frying it. For seafood and veggies, however, I like a beer batter or tempura batter (they are very similar). Batters coat food more evenly and make a thicker coating. They are wet, so it takes longer for the oil to drive off all the moisture, but in that time, steam bubbles up in the batter, making the finished coating lighter and crispier. Carbonated liquid such as beer in the batter makes it froth even more in the oil, creating a lacier finish.
J. Kenji Lopez-Alt of SeriousEats.com preaches substituting some of the beer with vodka because it evaporates faster during frying, and I am a Kenji acolyte. The vodka also inhibits gluten formation in the batter and that keeps the mixture liquid longer as you are working with it. The alcohol in the beer and vodka is driven off during frying, but if you must, you can substitute club soda or seltzer water. Just don't use anything with sugar in it. And before you start battering and frying, read my article on frying here because it's soooo much better to fry on the grill.
Tempura Batter Fried Vegetables And Seafood Recipe
Try this batter on veggies such as zucchini, green beans, mushrooms, pickles, Brussels sprouts, peppers, onion rings, eggplant, okra, and green tomatoes sliced about ¼” thick. For seafood, try shrimp, squid, crab, lobster, or any white fish such as perch or cod.
Makes. About 6 cups vegetables or 4 pounds of seafood.
Takes. 15 minutes to make the batter, 10 minutes to fry.
For frying and serving
Enough vegetable oil to fill the frying pot or pan 1” deep
6 cups vegetables or 3 to 4 pounds of seafood, depending on how small the pieces are
Coarse salt for serving
Dry ingredients for the batter
2 cups cake flour
1/2 cup cornstarch
2 teaspoons Morton’s kosher salt
2 teaspoons baking powder
1/2 teaspoon baking soda
1 teaspoon onion powder
Wet ingredients for the batter
2 large eggs
12 ounces beer or club soda
4 ounces 86 proof vodka
About the flour. Cake flour is lower in protein and forms less gluten that all-purpose flour. It works best. Too much gluten can make a heavier bready coating. That said, if you don’t have cake flour, you can use all purpose flour. Nobody will die.
Optional. Add some seasoning if you wish. Try 1 teaspoon of hot pepper powder and/or sage.
1) Chill out. Chill the beer or club soda. Cold temps help prevent gluten formation.
2) Fire up. Preheat a 1" depth of oil to 375°F, preferably in a cast-iron Dutch oven on your grill.
3) Batter up. Mix the dry ingredients in a small bowl. Beat the eggs lightly in a large bowl. Add the rest of the wet ingredients to the eggs and stir. Pour the dry ingredients into the wet and stir but don’t mix aggressively: you don’t want to form gluten. Some clumps of dry flour should still be floating around in the batter, and the consistency should be a bit thinner than pancake batter. When you dunk something in it, the batter should coat the food thoroughly as excess batter gradually drips off. The batter should not be so thin that it immediately sheets off the food. If you need to thicken it, gently stir in more flour. To thin it, add beer, club soda, or water.
4) Dunk. If you are frying peppers or other pods (like okra), poke some holes in them so they don't explode. Drop the veggies into the batter and stir until coated.
5) Cook. With tongs, pull the veggies out, let some of the excess batter drip off, and slip the veggies into the oil. Try to cook pieces of similar thickness together so they are done at the same time. Do not crowd the pot or the oil temp will drop too low. Try to keep the oil temp above 325°F. Flip the veggies often and fry until the batter is pale golden in color, 1 to 2 minutes. If you are doing chicken this way, fry until the white meat reaches an internal temp of 160 to 165°F or the dark meat reaches 170 to 175°F. Don't worry about the temp of veggies and seafood. They will be safe when the batter is golden. When done, lift the food out with tongs or a spider strainer and spill them onto the grate or paper towels to drain and drip dry for a minute or two.
6) Serve. Sprinkle with coarse salt and serve. Scoop out any bits of fried batter left in the oil before the next batch goes in. These crunchy bits are called tenkasu and can be used in sandwich wraps, as toppings for noodle dishes, and as garnishes for soups.
