Prepare the peas: Bring a small pot of salted water to a rolling boil. Add the shelled spring peas and blanch for 45–60 seconds — just until they’re bright green and tender-crisp. Immediately transfer the peas to a bowl of ice water to stop the cooking and preserve their color. Why: Blanching briefly enhances the peas’ sweet vegetable flavor and keeps a pleasant bite; shocking in ice water stops carryover cooking so they don’t go mushy.

Make the lemon ricotta spread: In a small bowl, combine the ricotta (6 tbsp for 2 servings) with 1 tsp of the lemon zest, a pinch of flaky sea salt and 1/2 tsp freshly cracked black pepper. Stir until smooth and fluffy — use the back of a spoon to press air into the ricotta. Why: Zesting the lemon into the ricotta lifts the dairy with bright citrus oils; seasoning ahead of time lets the flavors meld and gives a creamy base that spreads easily on the toast.

Toast the sourdough: Heat a skillet over medium-high heat and add a thin smear of butter or a drizzle of olive oil. Toast the thick sourdough slices 1–2 minutes per side until the crust is deeply golden and the interior has some chew. Alternatively, use a toaster or oven at 425°F/220°C for 4–6 minutes per side. Why: A well-toasted slice provides a crunchy contrast to the creamy ricotta and runny yolk and the light caramelization adds a nutty, savory note.

Warm and dress the peas: Drain the blanched peas and gently pat dry. Toss them with the remaining 1 tsp lemon zest, 1 tsp extra-virgin olive oil, the chopped mint (2 tbsp) and half the chopped chives (1 tsp). Season with a pinch of flaky sea salt and a small crack of black pepper. Why: Dressing the peas after blanching adds a fresh herb lift and gentle acid that complements the ricotta without making the peas soggy.

Poach the eggs: Fill a wide, shallow pan or skillet with 3–4 inches of water and bring to a gentle simmer — small bubbles should rise steadily but the water must not be boiling (too vigorous water will batter the whites). Add 1 tbsp white vinegar per 1–2 quarts of water to help the whites coagulate (optional but helpful). For each egg, create a gentle whirlpool with a spoon, slip in the cracked egg close to the water’s surface, and cook for 3 to 3½ minutes for a tender white and very runny yolk (cook 3½–4 minutes if you prefer slightly set yolk). Remove with a slotted spoon and drain on paper towels. Why: Low, steady heat and a whirlpool encourage the egg white to wrap around the yolk for a neat poached egg; cooking time controls yolk consistency.

Assemble the toasts: Spread an even layer of the lemon ricotta onto each toasted sourdough slice (about 3 tbsp per slice). Pile the dressed peas on top of the ricotta, leaving a small well in the center for the egg. Carefully place a warm poached egg on each toast. Drizzle each toast with 1 tsp extra-virgin olive oil and sprinkle with the remaining chopped chives, a few fresh mint leaves, pinch of flaky sea salt, freshly cracked black pepper and a pinch of crushed red pepper or Aleppo if using. Why: Building the toasts in this order ensures textural contrast — creamy, then tender-vegetable, then luxurious egg — and seasoning at the end highlights all the flavors.

Finish and serve: Let the assembled toasts rest 30–60 seconds so the ricotta softens slightly. Serve immediately while the egg is still warm and runny; instruct diners to pierce the yolk and let it drizzle through the peas and toast as they eat. Why: Slight resting time melds temperatures and allows the yolk to mingle with the lemony ricotta for a silky, saucy bite.
