Preheat oven to 350 degrees. In a medium-sized mixing bowl, blend together the matzoh meal, flour and farina. Set aside. Dice the carrots, celery and onion into a blender container. Add the eggs, oil, salt, pepper and paprika. Blend until smooth. Combine the vegetable mixture with the dry ingredients in the mixing bowl. Blend well. Divide in half. Form the mixture into 2 rolls about 12 inches long and place each on a piece of very lightly greased aluminum foil. Wrap each roll in the foil securely. Place the rolls on a baking sheet. Bake for 45 minutes. Serve hot. Note: "Nyafat" is a brand name imitation schmaltz available in the kosher section of the supermarket. For those unfamiliar with it, it's an onion-flavored vegetable shortening and can be substituted for real schmaltz (rendered chicken fat). The advantages are (1) lower cost, (2) no cholesterol, (3) contains no animal products ("pareve").
