I have never been so relieved to see a red wooden house in my life. After seven hours of driving from Gothenburg, a wrong turn somewhere near Karlshamn, and a spectacular argument with a sat nav that seemed determined to send me into a lake, I finally pulled up at the Ronneby/Backaryd cottage with nothing but a crumpled bag of crisps in my stomach and a dangerously low tolerance for technology.

The mishap came within minutes of arrival. I had stopped at a supermarket in Ronneby to stock up, feeling terribly organised with my reusable bags and vague plans of cooking proper Swedish meals. I unpacked everything onto the kitchen counter with the satisfaction of someone who absolutely never does this at home. Fresh herring, new potatoes, dill, cloudberry jam, a wedge of Vasterbotten cheese that cost more than my first car. Then I opened the oven and realised I had bought precisely nothing that required an oven. The hob worked fine, of course. But there I stood, holding a beetroot salad and a frozen gratin that would remain frozen for three more days because I am, fundamentally, an idiot abroad.

The cottage kitchen, though, forgave me instantly. It is the sort of compact, well-equipped space that makes you want to be a better cook than you are. Proper knives. A coffee maker that actually produces coffee rather than brown sadness. Windows that look out towards the Blekinge countryside, where everything appears slightly too green to be real. I made coffee, sat at the wooden table, and ate cold herring on crispbread while feeling unexpectedly pleased with myself.

The following morning I found Ronneby's market, a modest Thursday affair near the square that immediately exposed my pretensions. I had been practising "tack sa mycket" like a performing seal, but the woman selling smoked fish simply handed me a sample and waited for my reaction. It was extraordinary. Rich, oily, nothing like the vacuum-packed versions I had accepted as normal. I bought more than I needed, which is the only honest response to discovering proper food.

Back at the cottage, I attempted proper cooking with the determination of someone who has watched too many television chefs. The new potatoes, boiled with dill and served with butter, were genuinely good. Simple enough that even I could not ruin them. The smoked fish needed nothing but a plate and my complete attention. I ate outside at the wooden table, watching the evening light do that particular Blekinge thing where it lingers for hours, golden and slightly show-offy.

By day three I had developed an embarrassing routine. Morning coffee with cloudberry jam on toast. A walk to work up an appetite that was already excessive. Then lunch constructed from whatever the market or the small Ronneby shops had provided. I discovered that Swedish cheese, left on the counter to reach actual room temperature, tastes of somewhere specific rather than generic dairy. I discovered that my attempts at pickling anything ended in vinegar-soaked disaster. I discovered that the cottage's simple kitchen was teaching me, slowly, that good ingredients need very little interference.

One evening I tried to recreate a dish I had eaten years ago in Stockholm. It involved salmon, cream, and a confidence I do not possess. The result was edible but apologetic. I ate it on the sofa, watching the darkness finally arrive around half past ten, and laughed at myself. This is what self-catering does, I think. It strips away restaurant performance and leaves you with your own competence, or lack of it, seasoned with whatever local butter you could find.

The gratin remained in the freezer when I left. Some things, I decided, were never meant to be.
