Dairy milk
Lactose-free dairy milk
Ordinary dairy milk with the lactose already broken down — steams like the milk it was made from, and tastes noticeably sweeter.
- Type
- Dairy
- Composition
- Same protein and fat as the dairy milk it is made from; the lactose is pre-split.
- Texture when steamed
- Indistinguishable from standard dairy of the same fat content when steamed.
What it is like to work with
Lactose-free milk is dairy milk treated with lactase, the enzyme that splits lactose into glucose and galactose. The proteins and fat are untouched, so it steams and foams essentially like the whole or semi-skimmed milk it started as — a useful thing to know, because it is often assumed to behave like a plant milk. What does change is taste: the simpler sugars read as considerably sweeter, which some people like in coffee and some find cloying.
How it behaves in the jug
Foaming and holding that foam are different properties, and a milk can be good at one and poor at the other. Ratings are coarse on purpose — the note beside each one carries the actual claim.

How sweet it tastes
Distinctly sweeter than standard milk even unheated, because the sugars present are perceived as sweeter than lactose.
Allergens and labelling
Still dairy. Lactose-free is not dairy-free and is not suitable for a milk-protein allergy — a distinction worth stating plainly when serving.
