I should have known the holiday was going to be eventful when I tried to unlock the wrong front door. There we were, me and my partner, standing in a narrow cobbled street in Grazalema, jiggling a key in a heavy wooden door while an elderly man peered at us from his balcony with the sort of expression that suggested this happened more often than you'd think. Fifteen minutes, one panicked phone call to the letting agency, and a very sheepish walk to the correct house three doors down. Turns out all these whitewashed Andalusian village houses look rather similar when you've been driving for four hours and your brain has turned to tapas.

The proper place, when we finally found it, was an absolute corker. A traditional townhouse with a roof terrace that looked out over the Sierra de Grazalema mountains, all jagged and dramatic against the blue sky. But I'll be honest, after the key fiasco, what I noticed first was the kitchen. Small, tiled in that classic Spanish blue and white, with a gas hob that looked like it had seen some action and a fridge that hummed with the determination of a pensioner on a stair climber. I had plans for that kitchen. Big plans. I was going to cook like a local, shop like a local, eat like a local. Basically, I was going to become a temporary Andalusian grandmother.

The next morning I marched down to the village market with an empty basket and a head full of ambition. The market itself was modest, tucked along a couple of streets near the main square, but the produce was something else. Tomatoes that actually smelled of tomatoes, fat green peppers, bundles of fresh thyme and rosemary, strings of garlic. I bought bread from a van that had pulled up and was doing a brisk trade, the loaves still warm, crusty and properly rustic. I felt quite the seasoned European, I can tell you, nodding along to rapid Spanish and pointing at things with what I hoped looked like confidence rather than desperation.

Back at the house, I attempted my first proper meal. Pan con tomate, that classic Catalan-Andalusian staple that looks so simple and is, in fact, a complete nightmare to get right. I grated the tomato, rubbed the bread with garlic, drizzled olive oil with what I thought was artistic flair. The result was soggy, aggressively garlicky, and somehow both underwhelming and overwhelming. My partner ate three pieces out of politeness, then quietly made himself a tortilla from the emergency eggs I'd bought. I ate my failure in silence on the roof terrace, watching the sun go down, and had a small word with myself about hubris.

The local shops saved me. There's a little grocer on one of the main lanes, family-run, where I started going daily just to practice my terrible Spanish and learn what to actually do with all this magnificent produce. The woman who ran it, Pilar, had the patience of a saint and the bluntness of a northern aunt. She told me my pan con tomate was rubbish because I used the wrong tomatoes. She sold me the proper ones, the ones that are more flesh than juice, and demonstrated the correct grating technique with the air of someone who had corrected many foolish tourists before me.

By day four I was doing respectable things with eggs and potatoes. The tortilla became my reliable friend, simple enough that even I couldn't ruin it, satisfying enough to eat for lunch with a hunk of cheese and some olives from the deli counter at the cooperative on the edge of the village. I discovered that local Grazalema cheese, made from sheep's milk, is sharp and crumbly and absolutely nothing like the mild stuff I buy at home. I put it on everything. Eggs, bread, straight into my mouth while standing at the open fridge like the classless creature I truly am.

One evening I attempted a proper pescaito frito, the tiny fried fish that Andalusia does so well. The fishmonger, open only in the mornings, sold me a bag of fresh anchovies so silvery they looked like they'd been polished. I floured them, fried them quickly in olive oil, served them with lemon wedges and a cold beer on the terrace. They were genuinely good. Not restaurant good, perhaps, but good enough that I ate the lot standing up, picking them up with my fingers, dropping crispy bits down my shirt like the elegant diner I am.

The village has a few proper restaurants, of course, and we did treat ourselves one night to a meal out, sitting in a square with tables spilling out from a place that had been recommended. I had rabo de toro, oxtail stew, dark and rich and falling off the bone, while my partner had a plate of jamon that he still talks about in hushed tones. But honestly? Some of my favourite eating moments were the self-catered ones. The breakfast of fresh bread, local honey, and coffee made in a battered stovetop pot that took forever and tasted all the better for it. The lunch of whatever looked good at the market, thrown together without much plan. The evening glasses of manzanilla sherry, slightly too warm because I'd forgotten to put it in the fridge, sipped while something simple bubbled on the hob.

On our last morning I made one final tortilla and took it up to the terrace. The mountains were hazy in the early heat, the village was quiet except for a dog barking somewhere and the distant sound of a scooter. I thought about how I'd arrived full of bluster and misplaced confidence, how a small humiliation with a door key had somehow set the tone for a holiday of gentle, necessary lessons. I wasn't going to become a Spanish grandmother in a week. But I could make a decent tortilla, buy a tomato with some knowledge, and eat a fried anchovy with genuine pleasure. Sometimes that's enough. Sometimes that's more than enough.
