Once the butter melts, reduce the heat to medium-low. At this stage, the butter will foam at the top – it’s totally okay.
Stir from time to time to avoid the butter from burning. Once it turns brown (it may take some time), remove the pan from the heat and let it cool for 7-8 minutes.
Pour the butter into a glass cup. Make sure to scrape the pan for all the brown bits there. Stir and mix well.
Use a silicone candy mold – pour the butter inside and freeze. Once frozen, pop them out and enjoy.
