Coca amb Tonyina Recipe: Alicante's Salty Tuna Flatbread
This page may contain affiliate links.

Coca amb tonyina is a savory flatbread from the city of Alicante, traditionally eaten during the San Juan festivities. A simple olive-oil dough is stretched thin, filled with salted tuna and sweet onions, then studded with pine nuts and baked until deeply golden.

The filling is remarkably simple, yet it delivers an intense, briny flavor that has made this coca a culinary symbol of the city. The dough comes together quickly with beer and olive oil, and it bakes into a thin, wonderfully crunchy crust.

Depending on the area of Alicante, the filling may carry more or fewer onions, or include other vegetables such as tomato or peppers. If you can't find the traditional salted tuna, canned tuna will work too, though the result won't be quite the same.

The contrast between the crisp crust and the savory, pine-nut-studded filling is what makes this coca so memorable. Once you've made it, it's easy to see why it's a festival favorite.

6. Bring the flour together

Add 500-550 grams of flour little by little. If the dough still feels a bit sticky after 500 grams, add the rest gradually until you have a moist dough that doesn't stick to the touch.

7. Let the dough rest

Let the dough rest for 30 minutes covered with plastic wrap so it doesn't dry out.

Tips for the Best Coca amb Tonyina

Handle the salted tuna carefully

The tuna used in this coca is tonyina de sorra, a part of the tuna usually sold dry or salted, which gives the coca its intense flavor. When you buy it, you may be advised to soak it in water for a while before making the coca, since otherwise it can taste too salty.

Keep the dough moist but not sticky

The dough should be soft and slightly damp without clinging to your fingers. Add the flour gradually and stop as soon as it reaches that point, then let it rest covered so it stays pliable and easy to stretch.

Adapt the filling to your taste

Depending on the area of Alicante, the filling can vary and include more or less onion or other vegetables such as tomato or peppers. Canned tuna can stand in for tonyina de sorra if you can't find it; the result won't be the same, but it still satisfies the craving for a delicious Alicante coca.

30 Favorite Recipes I Keep Coming Back To at Home

Universal Meals: Recipes

Maybe you're wired the same way I am: your kitchen rotation is a blend of cozy standbys, well-loved dishes from around the globe, and sweets that make a crowd happy.

Some nights I want something luxurious, and that's when I reach for this La Viña Molten Cheesecake recipe, this refined Original French Crème Brûlée recipe, or a deeply rich Chocolate Mousse Cake recipe. And on days when only fruit-forward comfort will do, this timeless French Tarte Tatin recipe is my reliable pick.

For quick morning meals and lighter plates, I regularly whip up these airy Oatmeal and Banana Pancakes recipe, a hearty Stuffed Sweet Potato recipe, or these bright Eggs Stuffed with Avocado and Salmon recipe. And whenever my pantry needs a gluten-free basic, this no-fuss Gluten-Free Rice Flour recipe does the trick.

On evenings built around tapas and Mediterranean tastes, I cycle through this punchy Basque Tuna with Tomato recipe, golden Patatas Bravas Air Fryer recipe, silky Tirokafteri Greek Dip Sauce recipe, and a cool Burrata Salad with Tomato and Pesto recipe. This elegant Italian Vitello Tonnato recipe also comes out whenever the occasion calls for a little extra polish.

For stick-to-your-ribs midday meals and comforting suppers, my go-tos are this warming Meatballs in Spanish Sauce recipe, time-honored Meatballs in Almond Sauce recipe, deeply savory Italian Bolognese Sauce recipe, and velvety Chicken Croquettes in Thermomix recipe. When I'm after something even more substantial, I turn to this oven-baked Greek Pastitsio Pie recipe, homey Potatoes and Squid Stew recipe, or the supremely cozy French Boeuf Bourguignon recipe.

Anytime street food or party fare is on my mind, I'll throw together this succulent Homemade Chicken Doner Kebab recipe, crunchy Salchipapas recipe, punchy Mexican Pork Carnitas recipe, or these crisp Korean Hobak Jeon recipe. These effortless Air Fryer Zucchini Rings recipe are another favorite of mine for a light starter or snack.

And when I'm hosting and mixing drinks to go with a full spread, dinner often gets paired with this cool Original Cuban Mojito recipe, a strong Long Island Iced Tea recipe, or a pitcher of this sweet Bleeding Spanish Sangria recipe. To bring it all together, I like setting out this zesty French Remoulade Sauce recipe alongside, or capping the meal with this dramatic Mediterranean Black Rice with Squid recipe.

On the sweet side, the lush, velvety Orange Chocolate Mousse Recipe is my pick when I want a dessert that feels fancy yet comes together without fuss. Another treat I adore is the caramelized Trdelnik Slavic Pastry Recipe, modeled on the celebrated Central European chimney cake. If baking is your thing, knowing how to make syrup for better dessert texture helps a lot, and my Inverted Sugar Recipe walks through exactly how I do it at home.

When light and easy is what I'm after, I lean on the timeless Italian Caprese Salad Recipe or a flawlessly done Simple Poached Egg Recipe. For more filling comfort fare, I frequently suggest the crowd-pleasing Meatball Sandwich Recipe, the luscious Russian Stroganoff Beef Recipe, and the speedy weeknight go-to One Pot Pasta Recipe.

Sharing dishes from across the globe is another joy of mine, among them the genuine Sorropotún de Bonito Fish Stew Recipe, crispy Chilean Pumpkin Sopaipillas Recipe, and the traditional Spanish Cochifrito Segovian Fried Pig Recipe.

Air fryer cooking is yet another category I turn to often, since it delivers speed without sacrificing texture.
