4 tsp. canola or vegetable oil, divided
1 large sweet potato
2 medium Idaho potatoes
1 medium onion
1 clove garlic, if desired
1 tbsp. fresh dill (or 1 tsp. dried)
2 egg & 2 egg whites (or 3 eggs), lightly beaten
1/4 c. flour (white or whole wheat)
1/2 tsp. baking powder
3/4 tsp. salt
1/4 tsp. pepper
1. Place oven racks on the lowest and middle positions in your oven. Preheat oven to 450°F. Line 2 baking sheets with aluminum foil. Spray each baking sheet lightly with non-stick spray, then brush each baking sheet with 1 tsp. of oil. (This provides a crispy exterior to the latke.)
2. Peel potatoes or scrub them well if you don't want to peel them. Grate potatoes. (The processor does this quickly.) Transfer them to another bowl. Use the processor to finely mince onion, garlic and dill. Add potatoes, egg, egg whites and remaining 2 tsp. of oil to the processor. Mix using quick on/off turns. Add remaining ingredients and mix briefly. If over-processed, potatoes will be too fine.
3. Drop mixture by rounded spoonfuls onto prepared baking sheets. Flatten slightly with the back of the spoon to form latkes. Bake uncovered at 450°F for 10 minutes, or until bottoms are nicely browned and crispy. Turn latkes over. Transfer pan from the upper rack to the lower rack and vice versa. Bake about 8 to 10 minutes longer, or until brown. Best when served immediately.
*Note: Alternatively, line the pan with parchment paper, such as Chefs Select. Bake uncovered at 425°F for 12 minutes. Ensure the paper does not extend beyond the baking sheet or touch the walls of the oven.
Serve with applesauce, low-fat sour cream or yogurt topped with minced lox and chives. Latkes freeze well.
