We all know that store-bought tomatoes taste terrible in the winter, actually they often taste pretty watery and bland most of the year unless your grocery store carries heirlooms or locally grown ones. Even then, they’re usually a far cry from ones picked right out of the garden. But there is an exception to this rule: grape tomatoes. They somehow taste good no matter what time of year it is. And in the dead of winter when your plate needs a little splash of freshness to get through the gloomy days, grape tomatoes are an excellent substitute for canned tomato products when making sauce.
