Due to a lack of pre-made southwest butter at the grocery store, the easiest way to score some southwest butter is by making it yourself. The good news is that southwest butter is easy to make and the ingredients are also easy to find. Head to the dairy aisle of a grocery store and pick out your favorite brand of butter. It may be easier to pick out a container of butter that’s already been whipped, since whipped butter is airy and easier to mix with other ingredients.
The rest of the ingredients can be found in the spice aisle and the produce section. Spice-wise, at a bare minimum, you’ll need salt, pepper, cumin, chili powder, and red pepper flakes. When it comes to herbs, you’ll need oregano and cilantro. To get more bang for your buck, dried herbs are the best bet. At the same time, fresh herbs have a scent and flavor vibrancy that’s often far superior to dried herbs.
The brand BetterButter sells what it calls Steakhouse Butter, which is somewhat similar to southwest butter. BetterButter’s Steakhouse Butter is made with ingredients like roasted red pepper puree, dried tomato, and onion powder. This isn’t quite the same as southwest butter, but it could be used as a butter base from which you could mix in additional spices and herbs.
