Mix together the salt, sugar, dried minced garlic
, dried minced onion, poppy seeds
, sesame seeds and zest
. Place the fish, skin-side-down, on a long piece of plastic wrap
. Splash with the vodka, and then pack the salt mixture on top of the exposed flesh. Sandwich the fillets
together, wrap well in plastic wrap, place on a baking sheet or baking dish
and refrigerate for about 1 day.
Remove the fish from the wrap, rinse well and pat dry. Slice the gravlax very thinly at an angle leaving the skin behind (see Cook's Note). Serve on bagel chips topped with sour cream or cream cheese. Garnish with poppy seeds, sesame seeds and sliced scallions.
