Vietnamese Yogurt (Da Ua / Sữa Chua)

Step 1

Combine about 25% of the milk and agar agar powder in a sauce pan and mix thoroughly. To warm and activate the agar agar, cook over medium heat until you hit a low boil for 1-2 minutes, then remove from heat.

Step 2

In a large glass or microwave safe bowl, combine the condensed milk and about 25% (same amount used earlier) of the milk and microwave for two minutes on high so they incorporate and warm up a bit, then stir well.

Step 3

Combine both mixtures above in the large bowl, then add all the remaining milk.

Step 4

Mix well and check the temperature to make sure it’s between 90-100 °F.

Step 5

Add in a five oz container of yogurt, stir well, then strain through a metal sieve or strainer to remove any large chunks.

Step 6

Split between jars for the yogurt maker and heat for eight to nine hours or even more if needed when the weather is cold, until it has enough of the sour yogurt taste to your liking.

Step 7

When ready, transfer to the fridge until cooled. Then it's ready to eat!
