I've spent the last hour on the web looking for a suitable recipe. The one chosen came from the BBC Food site (not to be confused with the BBC Good Food site): roasted halibut on a spring onion rosti with sorrel beurre blanc.
The joy of this recipe is that the early stages can be carried out in advance and then the finishing stage takes only 15 minutes. This means that I can have everything prepared and then finish off the dish when the Handyman comes in from the garden (which is pretty late in the evening whilst he's engrossed in his latest project)...so I'm off to start cooking. I'll post the recipe and some photos of the finished dish tomorrow...wish me luck!
