Cube a large potato and an onion. Then put in a food processor and chop until grated. Add egg and mix. Remove to a bowl and add the can of salmon. I washed the salmon off to remove the salt as much as I could. This optional. Then I mixed the salmon and potato mixture and slowly added matzoh meal until mixture was solid enough to make patties. After I made patties then I dipped each patty into a dish of matzoh meal. Coating all around. Let the patties stand for a while. It is a good idea to chill them for about 1/2 to 1 hour to set. Then fry patties in hot oil until brown and turn to the other side and brown. About 10 minutes on each side. This made me 8 patties. I drained the patties on paper towels.
