My second experiment this week was to freeze a fresh cod fillet to see if it would work with a traditional potato latke-styled recipe...and it did! I cooked these in peanut oil and I think they came out really well. The ratio of cod to potato I used was 1:2; I did not experiment further to see what the results would be playing with those proportions. I did experiment with panko vs flour, and decided I preferred the results with flour. —Sagegreen
What You'll Need
peanut or olive oil for frying
fresh cod fillet, folded and frozen
russet or Yukon gold potatoes (to yield @1 cup grated)
medium yellow onion (to yield @ 1/2 cup)
ground white pepper
lemon zest, to your taste
grated horseradish root
chopped fresh dill
chopped flat leaf parsley
grated horseradish root, or prepared horseradish
sprigs of fresh dill for garnish
After the cod fillet has been frozen, grate it using the large holes of a box grater. By folding it first before freezing, you can get a better grip then for grating. You can guard your hands from the frozen fish by wrapping the top of the fillet with paper towels.
Grate the potatoes with the skins on or off. I like to leave the skins on. Next grate the onions. Combine with the grated fish. Add 1 tbl. horseradish as well as the salt, pepper, and lemon zest.
Squeeze as much liquid from this mix as you can using a colander, cheesecloth or your bare hands. In a bowl mix the wrung out mess with half of the chopped herbs, the egg and flour. From this mix form about 10 fish cakes. These will be about 4 inches or so wide and at least 1/4 inch thick. Feel free to vary the size to your needs. For a light appetizer these can be made smaller.
To make a tartar sauce, blend the other half of the chopped herbs with the capers, 1 tsp.horseradish, mayo and sour cream. Chill until serving. You may have some leftover, or not.
Heat a heavy gauge frying pan with a generous coating of oil. When sizzling add half of the latkes/fishcakes. Press down gently on each one. When golden brown on the bottom , flip over. Press down gently and cook until golden brown all around. Make sure these are cooked in the middle before draining on paper towels. Cook the second batch the same way. Be sure to add more oil first, if needed.
Plate the warm fish cakes or latkes with the tartar sauce and fresh sprigs of dill.
