Chapter 2: Cold Tapas
If you want to understand the soul of a Spanish tapas bar, look past the hanging jamón and order the Ensaladilla Rusa. Every joint in Spain serves it, but the great ones treat it like high art. This isn't the heavy, cloying potato salad of American summer picnics—it's an exercise in texture and luxury, relying entirely on the pedigree of its components. We borrow a brilliant technique from Madrid's award-winning bars: roasting the potatoes instead of boiling them to ensure they remain dense and never waterlog the dressing. But the absolute non-negotiable is the Bonito del Norte—line-caught white tuna from the Cantabrian Sea packed in liquid-gold olive oil. Do not substitute water-packed supermarket tuna; the rich, fatty oil from the tin is the secret ingredient that emulsifies into the mayonnaise. Make this the morning of your party; it needs hours in the fridge to meld, giving you the perfect, stress-free cold anchor to offset the high-heat hustle of your hot tapas.
Before you start
Roast the potatoes and carrots.
Preheat your oven to 400°F (200°C). Pierce the unpeeled potatoes a few times with a fork and place them on a baking sheet alongside the peeled carrots. Roast until fork-tender—about 30 minutes for the carrots and 45 minutes for the potatoes.
Hard-boil the eggs.
Boil four eggs for exactly 10 minutes. Immediately transfer them to an ice bath to cool completely before peeling.
Cool and brunoise the vegetables.
Let the roasted potatoes cool completely at room temperature, then peel off the skins with your fingers. Cut the potatoes and carrots into a neat, uniform 1/4-inch dice.
Ingredients

- petite peas1/3 cup
- Bonito del Norte tuna in olive oil7 oz
- Manzanilla olives1/4 cup
- piparras2 tbsp

- black pepper1/4 tsp
- egg1 large
- neutral oil1 cup

Method
- 01
Assemble the salad base.
Halve the hard-boiled eggs, reserving the yolks for garnish, and finely chop the whites. In a large bowl, combine the diced potatoes, carrots, egg whites, thawed peas, chopped olives, piparras, and capers.
- 02
Prepare the Bonito del Norte.
Carefully drain the rich olive oil from the tin of tuna into a liquid measuring cup. Gently flake half the tuna into the vegetable bowl, reserving the largest, most intact flakes for the final garnish.
- 03
Build the potentiated mayonnaise base.
In a tall immersion blender cup, combine the raw room-temperature egg, mashed anchovies, sherry vinegar, olive brine, and piparra brine.
- 04
Emulsify the dressing.
Add the neutral oil, Arbequina olive oil, and the reserved tuna oil to a measuring cup. Insert the immersion blender all the way to the bottom of the egg mixture, turn it on high, and hold it perfectly still until a thick, white emulsion forms. Slowly pull the blender upward, pouring in the oil mixture in a thin, steady stream until you have a thick, highly flavored mayonnaise.
- 05
Dress and chill the salad.
Gently fold two-thirds of the mayonnaise into the vegetable mixture using a silicone spatula, taking care to coat the ingredients without mashing the potatoes. Smooth the top, cover tightly with plastic wrap pressed directly against the surface, and refrigerate for at least 4 hours.
- 06
Mask, garnish, and serve.
When ready to serve, transfer the chilled salad to a shallow bowl and mask the top with the remaining mayonnaise. Push the reserved egg yolks through a fine-mesh sieve directly over the surface to create a velvety golden layer, then top with the reserved tuna flakes, a drizzle of olive oil, a pinch of Pimentón de la Vera, and extra piparras.
Notes
Respect the resting time.
The 4-hour chill in the refrigerator is not a suggestion. It gives the roasted starches time to absorb the complex brines from the mayonnaise, locking in that authentic tapas-bar flavor while keeping you free to focus on the high-heat dishes.
Source the right tuna.
Generic water-packed albacore will obliterate the texture of this dish. You need Bonito del Norte or Ventresca packed in olive oil; the rich packing oil is a critical flavoring agent for the emulsion.
Control your starch.
Do not boil diced, peeled potatoes. Roasting them whole in their skins acts as an osmotic barrier, ensuring the potatoes stay dense, waxy, and structurally sound against the heavy mayonnaise.
