Prep the citrus and avocado: Zest the blood orange first (you'll use the zest to boost aromatic oils) then segment it by cutting away the peel and membrane and sliding the segments out over a bowl to catch the juices. Reserve any juice. In a small bowl mash the half avocado with a fork to a slightly chunky consistency; season with a pinch of flaky salt and a squeeze of reserved blood orange juice or a little lemon to brighten and slow oxidation. Why: Zesting before segmenting preserves the aromatic oils in the zest; a bit of acid in the avocado keeps color fresh and adds lift to the rich avocado.

Char the shallot: Heat a small skillet over medium-high heat until shimmering. Add 1 tsp extra-virgin olive oil and add the thinly sliced shallot in an even layer. Let them sit without moving for 60–90 seconds until the edges are deeply caramelized, then toss and cook another 30–60 seconds until charred in places. Remove to a plate to stop cooking. Why: Charring instead of soft-sweating concentrates the shallot's sweetness and adds smoky depth that complements the blood orange and avocado.

Toast the sourdough: While the shallots rest, toast the sourdough slice until it’s deeply golden and crisp but not burned (use a toaster or the skillet used for shallots). If using the skillet, wipe it, add a little oil or a smear of butter and fry the bread 30–60 seconds per side to develop a crunchy, flavored crust. Why: A sturdy sourdough base provides contrast to the creamy avocado and catches runny yolk without getting soggy.

Poach the egg: Bring a medium saucepan of water to a gentle simmer (small bubbles, not a rolling boil). Add 1 tsp white wine vinegar — this helps the egg white coagulate quickly. Crack the egg into a small cup. Stir the water to create a gentle whirlpool and slip the egg into the center. Let it cook undisturbed for 3 minutes for a soft set white and runny yolk (4 minutes for slightly firmer). Remove with a slotted spoon and drain on a paper towel. Why: The gentle whirlpool helps the white wrap around the yolk and vinegar tightens the proteins so the egg holds together.

Assemble the toast: Spread the mashed avocado in a thin, even layer on the toasted sourdough (thin layer prevents the bread from becoming soggy). Arrange blood orange segments on top — tucking them around the edges creates color contrast and ensures you get citrus with each bite. Scatter the charred shallots and sliced jalapeño (if using). Carefully place the poached egg in the center.

Finish and season: Sprinkle the pinch of smoked paprika over the egg and avocado to add a smoky warmth; scatter the chopped cilantro and a few flakes of sea salt; grind fresh black pepper. If desired, squeeze a little lemon over the whole toast to brighten flavors. Why: Salt and acid awaken the flavors, smoked paprika ties the citrus and char together, and cilantro adds a fresh herbal lift.

Serve immediately: Use a spoon to gently break the yolk so it spills over the avocado and bread. Serve at once so the textures remain distinct—crispy toast, creamy avocado, and runny egg yolk. Why: Immediate serving preserves the contrast of textures and the visual impact of the runny yolk.
