I make a lot of soups, some terrific, some tasty, some what-was-she-thinking, and never the same.
My favorite recipe is the Craig Claiborne Spaghetti with Anchovies and Clams -
But, I rarely get to use real clams in the shells, or even real salted anchovies, so CC's probably worked out better. I add less anchovies, more garlic, and definitely more hot chile flakes than he did. On the other hand, available pastas tend to be better nowadays.
Years ago I was imagining opening a soup and salad fast food type place. I thought if I could do it, it would just work, at least in west Los Angeles. But, I was never so serious about it that I really considered doing that. And given warmish summers, I'd have had to come up with an alternative to soup - easy enough now, egads, there is a taco place in Costa Mesa that I'd like to fly off to tomorrow - but it was back in the seventies or early eighties that I was envisioning that.
