The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

What each ingredient does
- Milk
- Forms the liquid base and carries the coffee flavor, adding body and mild sweetness.
- Ground coffee
- Supplies the coffee flavor and aroma that the milk takes up during boiling.
- Isinglass
- Acts as a fining agent, binding fine particles so they settle out of the liquid.
The step that matters
Pour off the liquid, leaving any sediment behind. Isinglass and coffee grounds settle into sediment during standing. Tipping or stirring the pot disturbs that layer and returns cloudy particles to the drink, so pour slowly and stop before the sediment reaches the spout.
