Preheat a small skillet over medium heat. Add 1 tablespoon butter to coat the pan. Add the ramps and cook 3 to 4 minutes, until translucent and just starting to brown. Add the garlic and cook 30 seconds longer. Remove from heat.
Arrange a sheet of wax paper on a clean work surface and spoon the butter into the center. Roll the paper around the butter, forming a tube and twist the ends to seal. Place in the fridge to harden until ready to use.
