This was adapted, doubled and adjusted from the Breuer's Teacher's Seminary cookbook. It won't win secular or year-round gourmet awards, but it makes yummy, simple and light Passover brownies that don't have an overly potato-starchy aftertaste. Our Passover utensils are limited: this uses only the mixer, a liquid measuring cup (also used to check the eggs) and a half-cup-sized dry measuring cup. The brownies come out about 1.25 inches high. All the best, CLKL
