Have a signature dish you love to make? Whip up a few batches and bring them to an LA Food Swap. Participants can mingle, taste each other's offerings and then trade—pickles for zucchini bread, preserves for pies. The swaps are free, save for a small service fee, but signups are limited, so check the LA Food Swap website often for swaps scheduled across SoCal. It's a great way to try new foods and get to know your neighbors—sweet deal.
