So why not try something similar with blackberries? I had the idea earlier in the week and have been waiting all week to give it a try...it was worth the wait. Busy week, so I'm glad I waited until Saturday when I had the time to make this dish the right way, because IT. WAS. GOOD. Success at my first attempt at any sort of a "reduction"!
This recipe takes a bit of prepping for the pork tenderloin so plan ahead...but it's worth it. Plus, this would make an excellent dinner party dish. Oh yeah, and it's low-fat and full of flavor...if your dinner guests aren't into healthy eating they'll never know!
Ingredients:
Pork:
- 1 unseasoned pork tenderloin, thawed
- Salt
- Pepper
- Rosemary
- Garlic powder
- 1 shallot, minced
- 2 tsp. olive oil
- 2 cups red wine (I used a Cabernet-Sauvingnon)
- 2 cups fresh blackberries (about 2 pints)
- 1 tsp. lemon zest
- Juice from one lemon
- 2 heaping Tbsp. seedless blackberry preserves, no sugar added
- 3 sprigs fresh thyme
- 2 tsp. sugar (see note in directions)
- salt & pepper to taste
Pork:
When ready to prepare the meal, take out the pork and it let come to room temperature. Meanwhile, preheat the grill (we use a charcoal grill, so I'm not sure of the temperature if you're using a gas grill).
When cooked, remove from grill, let rest for 5-10 min. and slice.
To make pork in oven, cover a shallow baking dish with foil and spray with cooking spray. Place pork on foil and bake at 350 degrees about 45 min. or until pork reaches 160 degrees.
Blackberry Sauce:

While waiting for wine/shallot mixture to boil, wash blackberries, put in a bowl and mash easily with a potato masher (otherwise blackberry juice will spray everywhere!). I did it in the sink to avoid any blackberry juice stains. Another option is to purée them in the food processor and then strain them with a fine strainer to remove the seeds. For a thicker sauce, use the potato masher. I would equate the mashing with "coarsely chopping" (i.e. still lumpy).
Once the wine mixture has reduced some (let boil about 5-8 min.), add freshly squeezed lemon, lemon zest, fresh blackberries, blackberry jam, fresh thyme, sugar (note: omit sugar if not using sugar-free jam), a dash or two of salt and some black pepper. Stir everything together, allow the jam to mix in well, and reduce heat to medium or medium-low. Simmer uncovered for about 30 min. or until sauce thickens to desired consistency, stirring occasionally.
Top sliced pork with blackberry sauce.
Sauce Makes about 8 servings. Because of my desire to eat this dish immediately, I didn't figure out exactly how much it makes, but I estimate it has about that many servings, based on our leftovers. The pork probably serves 4.
Review:
As mentioned above, THIS DISH ROCKS. I will certainly be making it again. Our immediate reaction was that the rosemary on the pork was an awesome complement to the blackberry sauce, coupled with the fresh thyme in the reduction. The garlic flavor was better off on the pork vs. the sauce, but surprisingly also went well. And of course, the red wine flavor ROCKED. Definitely a great combination and one I will be repeating.
We generally bake our pork tenderloins, but I'm really glad we grilled this one. The grill gave it an awesome flavor boost, but I don't think it would be lacking if it's baked. The key would not to overcook it, because the juiciness in the pork added quite a bit.
Nutritional information:
Blackberry reduction: 86 calories, 1.3 grams of fat, 2.1 grams of fiber per serving. Makes 8 servings.
Pork tenderloin: 122 calories, 3 grams of fat, 0 grams of fiber per 3 oz. serving.
(Note: this is a point to pay attention to serving sizes, as a few slices is probably a few servings. A food scale comes in handy just to get an idea exactly how much your serving weights, to accurately count the calories or WW points).
Where's the inspiration?
As mentioned above, I initially got this idea from a blueberry recipe I read, although this recipe was nothing like that one. I searched quite a bit online for a blackberry sauce I could use, but had a terrible time finding a recipe that didn't call for butter. I didn't think this needed butter...I was able to find enough alternative flavor-boosting sources for much less calories. So, the recipe is somewhat inspired and adapted from this one.
Really though, a WW-friendly-cooking friend had made a similar reduction with figs, so I chatted with her about how she made the sauce and went from there. So thanks to her for the inspiration!
Enjoy!
