Pluots, a fruit that’s a cross between a Japanese plum and an apricot, make a great compliment to juicy, flavor-rich tomatoes. Use plums or nectarines in place of pluots if you can’t find them.
Preserved lemons, featured in the dressing, are created curing by lemons in salt, sometimes with other spices. You use only the skins of the lemon, not the pulp or juice. They’re often an ingredient in North African cuisine and are available at Middle Eastern specialty stores and gourmet shops.
