For an even richer flavor, consider browning the pork tenderloin in a skillet before placing it in the slow cooker. Serve with a side of fluffy white rice or, for an extra layer of flavor, a lightly curried rice. The sauce can be thickened after cooking by transferring it to a saucepan and simmering until it reaches your desired consistency. Feel free to adjust the amount of curry powder to suit your personal taste preferences. Pork loin, or even a pork shoulder, can be substituted for the tenderloin, adjusting cooking time as needed.
