Let me start off I know how to cook, I actually now what to be a cook... I think... anyways... I can't cook for dates, food normally comes out bad, REALLY bad.
If you're a good cook who can't cook for dates, it's probably because either you're taking on too much or having difficulty concentrating on the recipe/timings while at the same time trying to keep the chit-chat flowing.
It's for this reason that either I stick with REALLY simple recipes if I'm cooking, or wait until a good few dates in when there's little of that initial awkwardness to distract you from the cooking. Personally, I think restaurants are a much better option early on.
If you do want to cook on a second date, stick to dead-easy/simple stuff or stuff that can be prepared earlier in the day and just needs finishing off.
There is no awkwardness, we act like we have known each other for years, it's very odd, but so is the whole relationship.

But yeah it's because I try to hard.
I'm terrible about this sort of thing, I tend to cheat. I would normally go for a pre-pared meal from Waitrose or Marks and Sparks if I'm hosting at home. Stick that in the oven, in your own (best) dishes of course, take it out at whatever time it says on the box, bottle of chilled champagne to go with it - nothing simpler. As long as you are buying good quality, fresh food, there is nothing wrong with pre-prepared meals, especially if it saves your guest from having to force down a botched dinner.
I wanted to cook him diner, he lives in a dorm and gets enough pre-made crap food from the dining areas.
I ended up making some lemongrass chicken, could have been a little more lemony, but he liked it. I made a marinade last night and let it sit in that. Then I added some more herbs while cooking, and it came out a very nice brownish color. I used birch beer to deglaze the pan, he loved that. I normally use Sprite (I don't have any wine), which also would be better for lemon chicken, but he really liked the birch beer, said it gave it a slight sweet flavor.
I then made orzo with garlic, onions, lemongrass, chives and lemon thyme. No flavor at all.

I really need some fresh basil and tomatoes (Only 8 months to go, and he won't be around here anyways!) and it would have been amazing, but whatever he enjoyed the chicken.
I also used a bag of really good microwaveable bag of mixed veggies to complete the meal.
We had grape juice to drink, because he had to drive back and is underage. Plus once again, no wine, not a huge drinker.
