Mmmmm................... roasted cauliflower. The blackberry marinade would go perfectly with pork tenderloin. I like to stuff pork tenderloin with sauteed shallots, garlic, herbs, pinenuts, eggplant caviar (just cooked eggplant mashed up) and something sweet to match the marinade....blackberries would work. Sear the tenderloin over high heat, then in a 400 oven until interior temp hits 150, then rest for 10 minutes. To stuff the tenderloin take your index finger and punch a hole down the center, then use something wider like the handle on a potato masher........put the stuffing in a pastry bag or a plastic bag with a corner cut off and squeeze the stuffing into the tenderloin. Cutting the loin into 2 pieces makes it easier and conveniently makes 2 servings.
Whether you think you can..... or you think you can't..... your 100 % correct.
