So for this week's recipes, I chose four appetizers that are easy-peasy to make but come across as having gourmet flavor. First up, raspberry balsamic meatballs. You can use store-bought meatballs here, or make your own from your own recipe, and then throw them in the slow cooker (even while they are still frozen) with a sauce made from raspberry preserves, balsamic vinegar, Worcestershire sauce, red pepper flakes and fresh ginger. This sauce is going to hit a lot of different notes, with sweet and tangy and spicy and umami, it's going to be delicious. And you can toss them in the slow cooker and just go back to them when the guests arrive.
