1. Soften the Butter: Remove the butter from the refrigerator and allow it to soften at room temperature until easy to mix.
2. Prepare the Cheese: Finely grate the cheese so it blends smoothly with the butter.
3. Combine the Ingredients: Place the softened butter, grated cheese, and cream cheese in a mixing bowl. Mix until creamy and evenly combined.
4. Add Seasonings: Add salt, black pepper, parsley, and minced garlic if desired. Stir well to distribute the flavours.
5. Adjust the Texture: Add a little milk if the mixture is too thick. Mix until it reaches a smooth, spreadable consistency.
6. Chill: Transfer the mixture to a clean, covered container and refrigerate for approximately 30 minutes to allow the flavours to blend.
7. Serve: Spread on fresh bread, toast, or crackers. Keep refrigerated and return it to the refrigerator promptly after serving.
