This recipe crafts an elevated take on sardines on toast, featuring a vibrant homemade tomato and sherry sauce, flaky tinned sardines, fresh diced tomatoes, shallots, and parsley, all served atop crispy sourdough with a peppery watercress finish. It's a quick yet sophisticated dish perfect for a light meal.
Elevate the sardine sauce by using intensely ripe, sweet tomatoes; their natural sugars will caramelize beautifully with the red onion. For a smoother sauce, blanch and peel the fresh tomatoes before dicing. Deglazing with dry sherry is crucial for adding a layer of sophisticated depth. When selecting sardines, opt for good quality, oil-packed varieties for richer flavor and texture. Ensure your sourdough is toasted to a perfect crisp-tender, providing structural integrity for the toppings. The fresh herbs and watercress are not just garnish; they provide a vital counterpoint of freshness and peppery bite, balancing the richness of the sardines and sauce.
