Habanero Compound Butter
This is not an intense, light-you-up heat, but a nice subtle burn that lets you know it's there, with a hint of garlic.
If you use salted butter you may not need to add salt.
You can toast garlic on the stove while letting your butter soften. Just cook over medium heat, turning often to keep from burning, until it's soft and lightly browned.
Can also be served in a bowl while still soft, rather than refrigerating.
Wear latex gloves when cutting chile peppers to prevent unexpectedly having irritating oil on your fingertips.
