I can bake!
When Lucinda and I got home this afternoon, there was a package on the porch. It was the new igniter for my oven. So I got out my tools and put it in. It was a bit of an ordeal, just because the two screws that hold the igniter to the side of the burner are at a very odd angle and very hard to reach. But aside from that, it was quite easy to install.
And it works just fine. So now I have a batch of focaccia dough rising to bake later this evening.
