My dad has a problem. It’s plagued him for years. He consumes this stuff more than just about anyone alive. He loves his cherry. Cherry what you ask? Cherry anything. He loves cherry ribs (wrapped in cherry bacon). His favorite smoke wood is cherry wood. He even puts maraschino cherry juice over his ice cream. So when we were brainstorming a recipe to do for Smithfield Pork, of course he had multiple options involving cherries. I had to reign him in a bit. Here is what the full title of the recipe should be: Cherry Smoked Pork Tenderloin Injected with Cherry Butter topped with a Maraschino Drizzle. We didn’t want to go overboard with the cherries, so we scaled it back a bit.

I partnered with Smithfield® Fresh Pork on this post because they want all of us to be grilling rock stars. So grab one of the many fine Smithfield pork products, from fresh ribs and pork tenderloin, to pork chops, to pre marinated pork which saves loads of time. Head out to Wal-Mart, like we did, and grab whatever it is that you are into and get after it. Always remember to grill and eat what you love. We live by that motto.

Pork Tenderloin Injected with Cherry Butter Ingredients:

  • 2 packages of Smithfield Fresh Pork Tenderloins (each package contains two tenderloins about a pound each or two pounds per package)
  • Salt to taste
  • 2 sticks salted butter, melted
  • 1/3 cup your favorite cherry flavored BBQ rub
  • Enough cherry rub to coat the pork tenderloins
  • 1/4 cup maraschino cherry juice (optional)

Pro Tip 1 ~ You will also need a mortar and pestle and a ball of bakers twine

How to prep pork tenderloin

Remove the pork tenderloins from the vacuum sealed packages. There will be a little trim needed, but not much. While the tenderloin has what looks like silver skin, by no means is it chewy, so don’t remove it.

But any fat chunks will need to be trimmed off:

Trimming fat from pork tenderloin
Most of the fat pulls away without any knife needed

This stuff is so tender that all I really had to do was get the edge free with the knife and then pull with my fingers and the fat came off in my hand. 

Once the fat is trimmed, hit the pork tenderloins on all sides with a coating of salt. Then line them up fat end to skinny and vice versa to tie them together:

Time to truss

Why tie pork tenderloins together?

Pork tenderloin is extremely lean. If we cook these individually, they will be done before we get much smoke flavor into them. By trussing them together, they insulate each other and can handle a lot more time in the smoke before they are ready for the sear. And by tying the skinny end to the fat and vice versa, we get a somewhat universal thickness that will allow both tenderloins to cook evenly. So let’s get at trussing these together.

For me, I cut a length of butchers twine and tie off one end:

One of two knots needed per pair of tenderloins
One of two knots needed per pair of tenderloins

Then create a series of loops down the length of the two tenderloins before tying off the other end. Form a loop around the meat and run the twine down a few inches to form another loop. Finally tied off at the bottom:

Four tenderloins trussed into pairs
Each of those two have just one knot at each end

Pro Tip 2 ~ This can also be accomplished with four shorter pieces of twine that are each tied off in a knot

What should I inject into my pork tenderloin with?

The easier answer would be what should I not inject with. Pork can be injected with all manner of liquids from root beer to pineapple juice. It could be herbal tea or a robust coffee. We could inject with beer, wine, or even bourbon. The possibilities are only limited to liquids that taste good! We decided to experiment with butter and cherry for this cook, which paired well with the cherry sauce we added at the end. 

How to make compound butter

Now let’s melt that butter in the microwave. While it is melting, we need to grind up that cherry rub or it will clog the injector:

A mortar and pestle
Time for that bump and grind

I’m not kidding on the clogging of the injector. We started with one injector, but the needle was too narrow of a gauge to pull in the butter and rub. We had to switch to a thicker gauge needle and injector. So work that mortar and pestle well. 

Now mix in the finely ground rub in the butter:

Dropping the rub into the butter
Drop the rub into the butter

Then give it a whisk:

Mixing up the cherry butter
You will need to keep whisking the cherry butter before loading up the injector each time

And then let’s get our cherry butter into that injector and into our pork:

Pulling cherry butter into the injector
Yeah thats a new injector with a bigger needle

And then poke the needle into the muscle but not all the way through and push a little bit of the cherry butter into the meat:

Injecting the meat
So many jokes that I wont make on a family website such as this

Notice my finger right over where the needle goes into the pork? That’s not an accident. 

Tip 3: Hold a finger over the hole and leave it there when you slide the injector out. Keep the pressure on for a few seconds and it will reduce the amount of butter that comes back out when the meat contracts.

Injecting the meat
It gets a little messy but dont worry well use that excess cherry butter later

Still, a good amount of the cherry butter will come back out. Don’t let that go to waste. Roll the trussed pork tenderloins around in the leaked butter until all the butter is gone:

Coat that pork with the excess butter

Then season the outside of the meat with more rub, the butter should act as an amazing binder:

Now season that pork with the remaining rub

Once the trussed pork tenderloins are injected and rubbed, it’s time to start the grill. You don’t have to use cherry wood here, but of course we did:

Cherry wood
Cherry wood because well cherry And proof yet again that we have a cherry problem

Any fruit wood would do here. While dad is partial to cherry, I love peach, pear, apple and apricot, all of which would be a great substitute here. A chunk or two is all you need:

How to grill pork tenderloin injected with cherry butter

Set up the grill for two zone or indirect grilling. Coals and smoke wood on one side, the meat on the other. Or the coals and wood on the bottom of a kamado with the plate setter in between the coals and the meat. Target temp inside the grill is 300F

Place the trussed pork tenderloins on the side with no coals and close the lid:

Now were cooking No really Now were cookin

Smoke the pork tenderloins until they reach an internal temp of 135F (according to my Thermapen). These took about 50 minutes:

Pork reading 135F
Ready to sear

Time to put the Sear in Reverse Sear

Now crank up the grill by opening vents, raising the coal bed (if possible), removing the plate setter, and/or add more charcoal, depending on your grill and what it takes to get the hot side up over 650-700F. In my case, I just raised the level of the coal bed and was good to go:

A temp gauge reading 710F

Now slap those cherry butter injected pork tenderloins over the high heat and get a char on them while taking the internal temp of the pork up to 145-150F:

Searing that pork
Sear that pork

Wait? 145? Yes, the USDA recommends that pork can be served at 145 so a little pink on that pork tenderloin is just fine. And trust me, it’s glorious and will change your life. 

Sear on the top and bottom:

Searing pork tenderloin
Just get a little browning or char on the outside

And don’t forget the sides:

Searing the sides
These pork tenderloins arent two dimensional Get the sides too

Then remove from the heat and allow to rest for 10 minutes or so:

Time for a rest

Cut away the butchers twine and slice. Now if you’re like dad, you haven’t gotten your cherry fill yet, so drizzle some maraschino cherry juice:

One of my favorite action shots ever

You could also make a glaze or drizzling sauce with some fresh cherries or just use them for decoration when plating along with some Swiss chard:

Pork tenderloin injected with cherry butter recap:

This is a wonderful combo of sweet and savory and most of all, juicy. The injector pushed the cherry rub and butter right into meat and it stayed there, to some degree, throughout the cook. Eat these medallions as they are, or slap them between a couple Hawaiian buns and make sliders. If you check the recipe card below, you will see that the this recipe serves 8-12. Not bad considering each package of pork was less than $10. That’s just over $1.50 per person plus a few other ingredients.
