In a small bowl, mix together the garlic powder and water to bloom the garlic powder. Set aside for 5 minutes.
In a separate microwave-safe bowl, scoop out 1 tablespoon of the unsalted butter from the ½ cup of softened butter, and melt it in the microwave for about 10-15 seconds.
Add the dried parsley, dried oregano, onion powder, ground cumin, salt, vinegar, and ground black pepper to the melted butter and stir until well combined. Also, add the bloomed garlic mixture.
Allow the mixture to cool and thicken for a few minutes.
In a separate medium bowl, add the remaining softened butter.
Add the melted butter mixture to the bowl with the softened butter and use a spoon or fork to mix all the ingredients together until well combined.
Transfer the garlic butter to a small bowl or container and refrigerate until ready to use. Enjoy!
Notes
Note A: Butter: To control the saltiness, use unsalted butter. If using salted butter, omit the salt in the recipe and adjust later. Note B: Garlic powder: Not to be confused with garlic salt. That has a lot of added salt content. Note C: Blooming and steeping: Blooming the garlic powder is a process of rehydrating that can enhance the garlicky taste. In the same way, steeping the herbs and spices in the melted butter can help to infuse their flavors into the butter. So don't skip these two steps.
