Towards the end of my stay with Nina, I asked her for her Tortilla Espanola recipe, which was my absolute favorite thing. She laughed a little - for her, something like Tortilla doesn't have a recipe, it's just something she can throw together with her eyes closed. But she humored me and explained how she makes it... and now, almost ten years later, I will still occasionally make it and think back to my time in Spain. It doesn't come out as pretty as hers, but the flavor is pretty close to how I remember it.
I found this recipe, which is more or less how Nina taught me (though it doesn't mention salt/pepper, which I always add rather generously), but I'm sure there are countless variations out there. This time I taught Didz how to make it... and in a few years, I'm looking forward to teaching Didzette.
I think she'll like it.
