Butter rendered and clarified is a fat used in cooking, baking or frying. It is liquid when heated, but it solidifies at cool room temperature or when refrigerated.

How long does it take clarified butter to solidify?

Let the melted butter sit for 10 minutes and then skim off the milk solids floating at the top with a soupspoon. Cover and refrigerate until the fat solidifies, which will take at least 4 hours.

Can melted butter go back to solid?

When you melt butter with heat, the emulsion "breaks" and the components separate. If you have leftover melted butter from a cooking or baking project you can put it back in the fridge and it will harden, but it will also remain broken.
