Heat metal sauce pan over medium high heat and add the butter.
Once butter has stopped sizzling and has completely melted, add the garlic.
Use a spoon to scrape the layer of foam off of the top.
Swirl in gently until you have clear, golden brown butter. Make sure you keep a close eye on it now. It can go from golden brown to burned very quickly.
Pour the brown butter into a bowl. Make sure you don't add the brown sediment that will be at the bottom.
Stir Yuzu Juice into the butter garlic sauce.
Taste and season with salt according to your preference. If you used unsalted butter, you will most likely want to add salt.
