What each ingredient does
- Parsley
- Provides the green color and fresh, herbal flavor of the butter.
- Butter
- Carries the parsley flavor and gives the finished spread a rich, smooth texture.
The step that matters
Gradually mix the parsley pulp into the butter. Adding the pulp slowly lets it disperse evenly through the fat, so the herb flavor and color spread through the butter instead of clumping in streaks.
