Pour cold, fresh milk into a jar, tighten

Then stabilize the foam: remove the lid,
place the jar in the microwave, and heat
on high for about 30 seconds, or until the
foam rises to the top of the jar.
In addition to its appealing texture, cream

molecules also found in coconut and peach

robust, forgiving ingredient. Milk contains
roughly equal weights of protein and fat,
while in cream fat outweighs protein by at
