TO CLARIFY

Removing suspended solids from a liquid or a fat, so what remains is clear and behaves predictably under heat.

Why it works

Two quite different operations share the name. Clarifying butter means separating its three components — butter is roughly 80% fat, 16% water and 4% milk solids — by melting it gently so they stratify, then keeping only the fat. Those milk solids are proteins and sugars, and they are what burns at around 150°C, so removing them raises the usable temperature to well above 200°C. That is the entire reason to do it. Clarifying a stock is a different mechanism: fine particles stay suspended because they are too small to settle, so an egg-white raft is used to trap them — the albumen coagulates as the liquid warms and forms a mesh that catches the particles as it rises. Straining alone removes what is large; only the raft removes what is colloidal. For a starchy liquid like horchata, the job is simply mechanical filtration, done twice.

How to tell

• Melted butter separates into three visible layers within a few minutes of gentle heat, with white foam on top and milky sediment below.
• The clarified fat is transparent gold — if it is cloudy, solids are still in it.
• A stock raft rises and sets into a grey crust with a clear opening; the liquid drawn from beneath it runs clear.
• A double-strained starchy liquid feels silky rather than gritty at the back of the throat.

When it goes wrong

Clarified butter still burns.

Milk solids carried over. Skim the foam properly and leave the last of the sediment behind rather than pouring everything off.

The stock went cloudy again after the raft.

It was stirred or boiled after the raft formed. Any agitation breaks the raft and puts the particles straight back in.

The butter browned during clarifying.

Too much heat. It should barely melt — browning here makes ghee, which is delicious and a different thing.

Horchata or a nut milk is gritty.

Strained once. The first pass takes hulls, the second takes the fine particles you actually feel.

Recovering it

Cloudy clarified butter can be re-melted and settled again, which usually finishes the job. A stock that has re-clouded can be clarified a second time with a fresh raft, though each pass costs some flavour. Gritty liquid is simply strained again. Butter that browned is not a failure at all — it is browned butter, and worth keeping for something else rather than discarding.
