Cut the crust from the white bread, cut the bread coarsely and soak in a little water. Remove the skin from the onion and grate finely. Peel the potatoes and press them through a potato ricer. Squeeze the bread and mix it with the grated onion, the mashed potato, the juice of one lemon, a little salt, olive oil and caviar. Blend everything in a hand mixer to a fine paste. Leave the entrée to cool until serving.
Author’s note: In Greece, taramó is prepared from reddish fish eggs, which unfortunately are not available here. I have therefore given the recipe with chum salmon caviar.
