Five Golden Rules for Thick, Firm Homemade Yogurt with a Creamy Top

Firm homemade yogurt with a thick layer of cream starts with the right milk. The guide recommends fresh, daily raw milk instead of boxed UHT milk, saying higher fat content directly improves the yogurt’s taste and quality.

The milk should be simmered in a wide pot over low heat rather than removed from the stove immediately after boiling. Airing the surface with a ladle helps excess water evaporate, producing yogurt firm enough not to collapse when a spoon is inserted.

Temperature is the most delicate part of the process. The milk should be neither hot enough to burn a little finger nor merely lukewarm. The suggested range is about 42 to 45 degrees Celsius, or a temperature at which one can count to seven after dipping in a little finger. If the milk is too hot, it can kill beneficial bacteria and leave the yogurt separated and watery. If it is too cold, the starter may not set.

The starter, about a teaspoon of good homemade yogurt, should reach room temperature first. Mix it smooth with a small amount of warm milk, then add it gently from the side of the pot without agitating the mixture too much.

Finally, wrap the pot in a thick cloth or blanket and leave it completely still for four to five hours. Uncover it and let it air at room temperature for one to two hours, then refrigerate it uncovered for at least 24 hours. This final resting period helps the yogurt absorb its liquid and become firm.
