Ingredients

• 2 cups stout beer, such as Guinness Irish stout
• 2 tablespoons canola oil
• 2 tablespoons soy sauce
• 1 tablespoon toasted fennel seeds
• 1 tablespoon light brown sugar
• 1 tablespoon finely chopped fresh thyme
• 8 cloves garlic, chopped
• 2 pounds lamb tenderloin, cut into 1/2-inch cubes
• Salt and freshly ground black pepper
• Honey Dipping Sauce, for serving, recipe follows
• 1/2 cup clover honey
• 1/2 cup Dijon mustard
• 1/2 cup whole-grain mustard
• 1/4 cup prepared horseradish, drained
• 1/4 cup fresh mint leaves, finely chopped
• 1 tablespoon fennel seeds, lightly toasted and ground
• Salt and freshly ground black pepper

Instructions

1. Special equipment: 6-inch wooden skewers, soaked in water 30 minutes
2. Whisk together the stout, 1/4 cup water, oil, soy sauce, fennel, sugar, thyme and garlic in a baking dish. Toss the lamb in the marinade to coat, and then cover and refrigerate at least 1 hour and up to 4 hours.
3. Preheat a grill or grill pan. Sprinkle the lamb with salt and pepper, and then thread 2 or 3 pieces onto each skewer so that the meat lays flat.
4. Grill the lamb until slightly charred and medium-rare, 2 minutes per side. Serve on a platter with the Honey Dipping Sauce on the side.
5. Whisk together with the honey, mustards, horseradish, mint and fennel seeds. Season with salt and pepper, and then cover and refrigerate at least 30 minutes to allow the flavors to meld.
