I think that what August said about "intent" is really the key here. If your intent is to make a tasty meal, and it happens to contain trace mounts of alcohol, but doesn't trigger you in any way, I think you're fine.
I guess I look at it from a parenting perspective. My kids are 7 and 9. I would never allow them to drink alcohol, but I would allow them to eat tiramisu. I guess, if I would allow my children to eat it then I wouldn't think eating it would impact my sobriety.
