Dear SOS: On a recent trip up to Marin County, we joined a few old friends at Marinitas. Oh, my. I’m not a ceviche lover, but this takes the town. This would be a great recipe to have, if you can get it out of her. If you can’t — I’ll call the NSA.
Dear Gary: Marinitas in San Anselmo, Calif., was happy to share its recipe, which you can find below.
