Spicy Whiskey Peach BBQ Sauce

Sweet and spicy, easy homemade Whiskey Peach BBQ Sauce (made with fresh peaches!) is the perfect condiment for your summer grilling.

We grill in the summer.  A lot.  So over the past few years, I’ve started making my own homemade barbecue sauces to slather on whatever we’re grilling.  I shared one recipe earlier this year — this chipotle rhubarb RhuBarBBQ sauce.  And now it’s time for another version!

This whiskey peach BBQ sauce initially came about because I had a batch of slightly too ripe peaches from our CSA last year.

And yes, this means that this sauce uses real peaches.  There are some peach barbecue sauces out there that use peach preserves.  If you can’t find fresh, use frozen peaches, but don’t use preserves or jam!

It’s so good, I now buy peaches and leave them out to purposely let them get a little soft just to make this.  It’s the perfect combination of sweet and spicy, and delicious on everything.  We’ve had it on pork, chicken, steak, and salmon, and even as a dipping sauce for sweet potato fries.  I can’t get enough!

Easy Homemade BBQ Sauce

Think homemade barbecue sauce is hard?  Think again.  It’s really just cooking down a bunch of ingredients in a pot and blending away.  That’s it.  

Cooked it too long?  Add water to thin.  Too chunky?  Blend a little longer.  Too spicy?  Dilute with a little water or another peach.  You can’t screw this up; I promise.

Fresh, extra ripe, juicy peaches simmered with brown sugar and whiskey until they practically melt.  The rest of the typical barbecue sauce ingredient gang is there, too — tomatoes, vinegar, mustard.  Plus a big splash of whiskey.  Actually, better make it a double splash, please and thank you.

You can peel the peaches if you so desire, but that’s an extra time-consuming step, so I never do.  Plus, you’re going to give everything a whirl in the blender, so really… save yourself the time.

Because I (and my toddler!) like things spicy, I added some sriracha to tone down the sweet peaches.  (“More chacha, Mommy! More chacha please?” – my 2-year-old).  If you’re not into spicy, leave it out, but it adds such a perfect little zing.

Adding Whiskey to BBQ Sauce

This is, after all, whiskey peach BBQ sauce. But why are we adding it? Just because adding bourbon or whiskey to everything is trendy? Of course not – there’s an actual benefit! It’s time for my favorite subject – kitchen chemistry to learn why!

(But first, I’ll make the important note that if you do not consume alcohol, this BBQ sauce is still delicious! Thin the sauce with chicken broth or even a little water at the end to reach the desired thickness.)

Kitchen Chemistry

Whiskey plays two major roles (in addition to adding new flavors directly from the whiskey): first, because alcohol is a solvent, it acts as a flavor carrier – meaning it can dissolve and extract flavors from other ingredients. The whiskey helps to enhance the aromatic compounds present in the peaches and spices. Second, alcohol is a cosolvent, which helps to increase the solubility of a poorly-soluble compound. In the case of our BBQ sauce, this means alcohol helps the fat disperse more evenly throughout the sauce, resulting in a smoother sauce texture.

After adding the whiskey to the sauce, continue to cook and stir the sauce for an additional 5 minutes. Alcohol has a lower boiling point than water, so even without bringing the sauce to a boil, some of the alcohol will start to cook off to provide an overpowering taste. However, remember that a small amount of residual alcohol will remain in the sauce!

Freezing Homemade BBQ Sauce

Want to make a huge batch of this while peaches are ripe? Go ahead and freeze the rest and enjoy it all winter long!  You can freeze it in glass mason jars, plastic storage containers, or my personal favorite: a plastic freezer bag so it lays flat and takes up minimal space.

Only want to thaw just a little bit at a time?  Freeze in ice cube trays, pop the frozen cubes out and store them in a freezer bag, and then pull out exactly how many you want each time!

When you’re ready to thaw, move the container to the refrigerator a day or two ahead of time and thaw in the fridge.  Set out at room temperature a few hours beforehand to bring it up to room temperature.

Because this sauce uses fresh peaches and isn’t properly canned, you don’t want to let it sit overnight at room temperature.

Tips and Tricks for the Best Spicy Whiskey Peach BBQ Sauce

  1. Use very ripe peaches to make the sauce.  We want the extra sweetness and soft texture!
  2. If it’s not peach season, use frozen peaches to make the BBQ sauce.  Do not use canned peaches or peach preserves.
  3. The sauce can be blended using a regular blender or a food processor, but an immersion blender is the easiest method and does not require pouring hot liquid into a new container.
  4. Peach BBQ sauce can be stored in the refrigerator for up to 1 month or frozen for up to 6 months.
