I cook very infrequently; at least, in terms of cooking meals that take any real effort. But, when I have cooked, I've surprised myself with how well it can go and how ambitious my meals are (given I have a recipe in front of me), so I went with reasonable. My best cooking ever was probably the one time I cooked braised rump steak in red wine sauce. Delicious, but it took an age to cook, and I was ravenous by the time I got it on the plate.
I also once made poached chicken breasts in white wine sauce with garlic and herb mash. Two fatal errors were made: the white wine I poached the breasts in and made the sauce with was sour and gave the sauce a horrible acidic tinge, and I forgot to fry the garlic, so the mash scorched your mouth, it was so potent. I'll never forget the pained looks on my parents' faces as they ate it. Effort appreciated, but that was about it!
