How can you use aludttej in cooking and baking?

What is aludttej?

Aludttej is a Hungarian fermented milk made from fresh milk that is left to ferment naturally with no other intervention. A fermented-milk guide says it is best made from fresh, preferably whole milk left at room temperature in a glass or clay container, with its own bacteria driving the fermentation over several days.

How do you eat it?

The guide describes aludttej as a cold drink: similar to kefir and very refreshing when served cold, especially in hot weather. It does not mention cooking with it. Left too long, it becomes quite sour, so check the container daily in summer.

Can you cook or bake with it?

We found no documented Hungarian cooking use. As general guidance only, any soured milk of similar thickness can replace buttermilk, kefir or thin yogurt in recipes where acidity is welcome:

• Pancakes and waffles: swap it one to one for buttermilk.
• Quick breads and cakes: it reacts with baking soda like other soured milks, so you can use it in the same amount as buttermilk.
• Marinades and dressings: mix with garlic, herbs and salt.

If the aludttej is very sour, taste the batter and add a little sugar.

The by-product

The guide notes that sour cream forms at the top of the container, where the milk fat collects. It is ready after about one day, while the aludttej itself needs more time.

A safety note

Aludttej relies on bacteria in fresh raw milk. Pasteurized milk does not work well, since heating kills those bacteria and the milk just spoils. Raw milk carries risks, so if you are pregnant, elderly, immunocompromised or giving it to children, buy a commercial pasteurized fermented milk such as kefir instead.
