MILK SUBSTITUTED FOR WATER
Milk contains proteins and sugars (lactose) that cause the mixture to foam and brown faster than water. Keep stirring to prevent scorching at the bottom.
COCONUT SUGAR TEMPERATURE
Coconut sugar has natural unrefined solids that burn at a slightly lower temperature than white sugar; target 295° F rather than passing 305° F.
TIMING THE LIME ZEST
Adding the zest at the moment of removal preserves bright citrus oils without boiling off flavor or turning bitter.
