Begin by preparing the bread base. Remove the crust from the day-old bread slices and soak the bread in water for about 5 minutes, or until soft. Squeeze out as much excess water as possible to prevent a watery dip, as taramasalata has a creamy consistency.
In a food processor or large mixing bowl, add the grated onion and softened bread. Pulse (or mix) the ingredients together until they form a smooth, even paste. This helps the flavours of the onion and bread to combine fully, creating a cohesive base.
Add the tarama (fish roe) to the bread mixture. Blend well on medium speed, until the tarama is fully incorporated and the mixture takes on a light pink colour. Ensure the roe is evenly distributed to achieve a consistent flavour.
Slowly begin to add the olive oil, one tablespoon at a time, blending continuously. Similar to making mayonnaise, adding the oil slowly helps to emulsify the dip, giving it a rich and creamy texture. Continue until you’ve added half of the olive oil.
Add the lemon juice gradually, tasting as you go. The lemon should add brightness without overpowering the tarama’s unique flavour. Balance is key in taramasalata, so adjust according to your preference, keeping the flavour fresh and zesty.
Resume adding the remaining olive oil in a slow, steady stream. Keep blending until the mixture becomes creamy and smooth. If the dip is too thick, add water one tablespoon at a time to adjust to your desired consistency. Traditional taramasalata should be creamy and spreadable.
Season the taramasalata with freshly ground black pepper to taste. Blend once more to incorporate the seasoning evenly. Taste and adjust lemon or pepper if desired, as both can enhance the overall depth of flavour.
Serve the taramasalata in a shallow bowl, garnished with a drizzle of olive oil. Optionally, add a few Kalamata olives or a sprinkle of fresh parsley on top for colour. Serve with warm pita bread, raw vegetables, or rustic bread slices for dipping. Enjoy this creamy, salty, and tangy dip as part of a meze spread or as a flavourful appetizer.
