Compound butter is one of those things that sounds daunting to make, but it really easy. Seriously. All you need is a butter, some herbs and/or vegetables and some additional seasonings (if you so wish). Oh, and either a really good mixer or food processor.
My favorite compound butter to make is a Rosemary/Sage/Thyme and Shallot blend.
To make my compound butter, I use my Nutri-Ninja | Ninja Blender Duo with Auto-IQ and the optional food processor attachment.
The powerful 1300 watt motor on the Ninja makes crafting compound butter a breeze! Especially if you forget to take the butter out of the fridge to let it soften (true story). In just a few pulses, your compound butter is ready to go on to whatever dish you like. I personally love putting an herbed compound butter on salmon and letting it melt as it bakes.
