Butter, Brown
Melt butter in saucepan over med-high. When it boils, reduce heat to medium, simmer until foamy. Continue cooking stirring occasionally and scraping bottom of pan, until foam subsides, butter turns golden brown with a nutty aroma, and milk solids separate into brown specks that sink to the bottom, 2-7 min (depending on the amount). Remove from heat; immediately transfer to a heatproof bowl. Make a big batch and freeze in ice-cube trays.
