How do I make Vietnamese Yogurt more tart?
I've been using several online recipes to make Vietnamese Yogurt. The ones I buy from the store are much more tart then my own results.
- Danactiv vanilla flavor - Way too sweet, but texture was alright
- 365 Organic Plain - Not too sweet, but not tart at all, texture was very thick
I have not been able to go to a store that sells Vietnamese yogurt due to the lockdown, so I didn't try that, yet. Hoping for an answer that allows me to make tart yogurt American grocery store ingredients.
Here's an example: https://www.youtube.com/watch?v=AgNtOOa8dg8
For incubation we used a warm water bath and left at room temperature (74F)
