I should have known the holiday was going to be eventful when I managed to get us lost before we'd even left Barcelona airport. Two hours of confidently ignoring the satnav, convinced I knew a "better route," and we ended up in what I can only describe as a very enthusiastic roundabout near Tarragona. My partner sat in silence, eating the emergency bag of crisps I'd promised we wouldn't need. Not my finest hour.

By the time we finally rolled into Sant Jaume d'Enveja, I was ready to abandon the hire car in a ditch and walk the rest of the way. But then there it was: our little holiday home, all terracotta roof and whitewashed walls, with the Ebro Delta stretching out behind it like someone had painted the landscape in a hurry and forgotten to add any hills. Flat as a pancake, green as anything, and absolutely reeking of wild rosemary and rice fields. I stood there with my suitcase, suddenly very aware that I'd spent the last three hours complaining about traffic while this place had been quietly existing without me.

The key was in a lockbox, which I fumbled with for an embarrassingly long time. My hands smelled of petrol station coffee and stress. Inside, the house had that particular stillness of somewhere waiting to be lived in - tiled floors cool underfoot, wooden shutters half-closed against the afternoon sun, a kitchen that immediately made me want to cook something ambitious and probably fail at it. I opened the fridge. Empty, obviously, but humming with potential. The previous guests had left behind a single lemon and what I choose to believe was a thoughtful gesture rather than an oversight.

We'd planned to eat out that first night, find somewhere local, be spontaneous. Instead I found myself in the tiny kitchen at half past eight, still in my travelling clothes, attempting a tortilla with three eggs, that lemon, and some olive oil I'd bought from a garage. It was terrible. Genuinely awful. Rubber in the middle, burnt at the edges, the kind of food that makes you question your life choices. We ate it on the little terrace anyway, swatting at mosquitoes and watching the sky turn that particular pink-orange that seems to happen properly only in southern Europe. My partner said it was "rustic," which I have learned is the highest form of culinary pity.

The next morning I was up early, determined to redeem myself. The market in Sant Jaume d'Enveja itself is small but fierce - local women with shopping trolleys and opinions, stalls heaped with tomatoes that actually smell of something, peppers in colours I didn't know peppers came in. I bought too much of everything, as I always do when abroad, convinced that this time I would cook like a local, eat like a local, be a person who knows what to do with a calcot. (I do not know what to do with a calcot. I have accepted this.)

Back at the house, I spread my haul across the kitchen table like a particularly edible crime scene. Bread from the bakery round the corner, still warm, which I tore into immediately like the animal that I am. Anchovies in oil, local rice in a cloth bag, garlic that made my eyes water just looking at it. I made a paella that afternoon, properly this time, following a recipe on my phone with the sort of concentration I usually reserve for tax returns. It was... fine. Better than fine, actually. The rice had that proper socarrat at the bottom, the caramelised bit that you're supposed to fight over. We fought over it. I won, because I cooked it, and I make the rules.

The days settled into a rhythm I hadn't expected. Mornings at the market or the little supermarket in town, afternoons attempting something I'd eaten the night before in a restaurant and decided I could definitely replicate. I could not definitely replicate them. There was a fideua that became a solid mass of noodles, a romesco sauce that separated like a failed science experiment, a fish stew that was actually perfect until I dropped half of it on the tiled floor. The five-second rule became the fifteen-second rule became "we're on holiday, it'll be fine."

What I learned, I suppose, is that self-catering isn't about being good at it. It's about the particular pleasure of failing in a foreign kitchen, of eating bread and tomatoes and olive oil that tastes nothing like home, of sitting on that terrace as the light goes and not caring that your arroz negre looks like something from a horror film. The Ebro Delta gave me flat land and big skies and ingredients I didn't understand. I gave it my best shot, and my best shot was frequently mediocre, and I wouldn't have it any other way.

On our last evening, I made the tortilla again. It was still not great, but it was better. Progress, not perfection, as they say. We ate it with some local wine, a white from somewhere nearby that I couldn't pronounce properly and didn't try to. The mosquitoes came back, the sky did its pink thing, and I thought about how I'd got us lost at the start of everything, how I'd stood in that kitchen with my terrible eggs and my stubbornness, how sometimes the wrong turn leads you somewhere you didn't know you needed to be.
