We add one beaten egg to the mashed potatoes and stir well. In a small bowl, we add the other egg and the water and whisk with some salt and pepper. In another bowl we add the rest of the bread crumbs and season them with a little salt and pepper. In the last bowl we add the flour.
We pick up some of the potatoes, a little less than 2 tablespoons and roll it into a cylinder. We use “standard breading procedure” to coat. We gently pat with flour, dip in egg wash, and then coat with bread crumbs. The croquettes are very delicate, so we do this gently! We place it on a wax-paper lined dinner plate as we continue with the rest of the potato mixture, forming 12 croquettes. We refrigerate these until it is time to fry.
We pre-heat the oven to 275 degrees. In a non-stick pan, we heat 1/4-inch of olive oil. When hot, we add half the croquettes and pan-fry on medium heat, turning a quarter turn with a spatula when the bottom is brown. We continue to turn until all sides are browned, about 5 minutes total, and then we drain on paper towels. After a minute we put these on an aluminum-foil coated cookie sheet in the oven. We add a little more olive oil to the pan and continue with the rest of the croquettes. When all of them are done, we keep them in the oven to keep warm until ready to enjoy!
