🧀 Baked milk

Baked milk is drinking milk that, after heating, is kept just below boiling point for several hours until it turns cream-coloured and gains a caramel note. In Ukraine it is a separate type of drinking milk: the Ukrainian standard DSTU 2661:2010 names four types — pasteurised, baked, ultra-pasteurised and sterilised. Baked milk contains 1 to 6% fat, and its colour ranges from light to dark cream, sometimes with a brownish tinge.

The colour and flavour come from the Maillard reaction: lactose reacts with proteins and forms melanoidins. Researchers at the national food university in Kyiv (NUFT) write that, under the current production instructions, the milk is kept at 95–99 °C for about 3 hours. Heating it for longer is not a good idea: excessive heating can produce undesirable compounds, so the process is stopped as soon as the milk reaches the right colour.

In Zinovia Klynovetska's collection “Dishes and Drinks in Ukraine” (1913), ryazhenka is made like this: milk is “steamed” in a glazed clay pot over moderate heat until it turns yellow, then cooled and mixed with sour cream. The folk names given there for the dish are parukha and pryazhanka. Under the Ukrainian standard DSTU 4565:2006, ryazhenka is a national fermented milk product made by souring baked milk specifically.

Baked milk or ordinary milk? This is drinking milk, not a dessert or an ingredient baked into a cake: in Ukraine the standard DSTU 2661:2010 counts it as a separate type, beside pasteurised, ultra-pasteurised and sterilised. After heating it is held just below boiling, at 95–99 °C, for about 3 hours, which gives a cream colour, sometimes brownish, and a caramel note, while pasteurised milk is heated briefly. Fat is 1 to 6%. Ryazhenka is not the same either: it is baked milk that has been soured.

On imported packs look for the Ukrainian words “пряжене молоко” or “топлене молоко” (baked milk), the standard mark DSTU 2661:2010 and the fat content, 1 to 6%. It is not sterilised, so it sits in the chilled dairy aisle, mostly in shops selling Eastern European food. Pouches keep for no more than 72 hours, bottles and cartons up to 7 days, at 4 ± 2 °C. The colour may range from light to dark cream.

Why it matters to you. On the label, look for the word “baked”, the Ukrainian standard DSTU 2661:2010 and the fat content. Like pasteurised milk, baked milk is stored at 4 ± 2 °C: in film pouches for no more than 72 hours, in bottles and composite cartons for up to 7 days. Baked milk is not sterilised, so do not leave it out of the fridge.
