Preheat the deep fryer to 356F. Green beans should be washed and dried well.
In a large bowl, whisk together Flour, Kosher Salt, Black Pepper, Ancho Chili Powder and Seltzer until smooth.
Add the green beans and stir until fully coated. When the oil is at temperature, add the green beans into the oil one at a time. It helps to hold the green bean by one end, then gently swirl the other end into the oil before letting go. They will sink, so try to place each one in a different spot. Work in batches, so you don’t stack the green beans. They will stick together if they stack.
They take 3-4 minutes to fry to a beautiful golden crisp. Remove them with a spyder or a fry basket. Shake off then place on top of paper towels. Sprinkle a bit of sea salt, if desired, while they are fresh from the fryer.
Serve fresh with honey mustard (you can use my recipe) or any dip you like.
Fried green beans can be saved and reheated, but they will not have the same delightful crisp. Plan to serve these hot and fresh.
