Welcome and cool on the PhD. I'm such a sucker for a man with letters after his name. But alas you are married. *chuckle* (No friends' lovers, no lovers' friends, no married men.)
I'll be reading your journal. I don't have any suggestions for your wife since while I do like playing in my kitchen, I was never an avid baker (too many ways to fail). But if I come across anything I think might help or encourage her, I will certainly post.
