In the space of a few weeks, food shopping options in Napa have exploded with possibilities and one of the most exciting of these is a tiny shop at the new Oxbow Public Market where Shuli and Ronit Madmone are selling spices — more than 300 kinds at last count, all gloriously fresh (they grind them at their warehouse in Petaluma). The array is visually dazzling — vivid green dill, bright Hungarian paprika, pale pink Himalayan salt, lavender powder — and in addition to spices both familiar and not, the Madmones create distinctive blends for curries, tagines and other exotic creations. And they know their products. Shuli’s family in Israel has been in the spice business for many years, and he brought that expertise with him when he moved to the U.S. Ronit, also a native of Israel, who met and married Shuli in Marin County, said she’s been “doing a lot of reading” in the library to build up her own spice knowledge.
