My California Dreamin’ sister is visiting New England and I’m pretty excited. Her plane has landed and she’s on her way. Greeting her at noon will be a familiar edible from our past. Our mother loved tomato jam and since the tomatoes at local farmers’ markets are at the peak of perfection, I decided to cook up a little surprise last night. It’s fun to browse through favorite tomato jam recipes online, but all I really needed for our favorite recipe were three main ingredients: tomatoes, lemons, sugar.
