In a small saucepan over medium heat, melt the butter until fully liquid and foamy, about 2-3 minutes.
Add the minced garlic to the melted butter and cook until fragrant and lightly golden, stirring frequently, about 1 minute. Be careful not to burn the garlic.
Pour in the honey and soy sauce, then whisk continuously until the mixture is smooth and fully combined.
Bring the sauce to a gentle simmer, then reduce heat to low and cook for 3-4 minutes, stirring occasionally, until the sauce slightly thickens and coats the back of a spoon.
Remove from heat and stir in the lemon juice and black pepper until fully incorporated.
Use immediately as a glaze for meats or vegetables, or let cool slightly before serving.
