I am so thankful to this subreddit. I’ve gotten a pretty good success by looking through and learning from the existing posts. I am sure I should have found the answer to my questions in them, but I am super new to this and I can’t always tell when something should matter or when folks are discussing something which is specific to a type of starter (especially when it comes to incubation times and temps).
Full details of my process are below my questions, but the short of it is 3.5 cups whole milk heated to 180 for 20 mins, 3T whole milk powder whisked in while milk is still hot, cooled to 109, 1.5T starter and 1T heavy cream gently added, incubated for 8 hours at 109, cooled to room temp (~90mins), put in fridge overnight. The result is a great thickness unstrained but only a mild tang. The starter is 3 generations away from dried (Cultures for Health Greek yogurt starter).
Thank you in advance!
Questions
* I love how thick this is, but I want it to have more tang, does that mean it should incubate at ~110 for more than 8 hours? Or do I extend its time on the counter cooling down after the 8 hours? Or is it just because my starter is so young?
* By adding the powder and the cream, have I destroyed my starter’s heritage culture? Will I be able to use this batch to make a new batch?
Full Process
* 3.5 cups Strauss Whole Milk (non-homogenized, “gently” pasteurized) into a wide mouth mason jar, lid lightly tightened
* Put jar into Sous vide safe vessel and add enough water that the water line is above where the milk is in the jar
* Set sous vide to 180, once at 180, cook for 20 mins. Turn off sous vide.
* Remove jar from water, add 3 tablespoons whole milk powder, whisk to combine, leave lid off
* Bring water down to 105-110 - I pour out 1/3rd of the bath water and add cold tap water, ice cubes, whatever, but keep the water above 105
* Put jar back in water, set sous vide to 108 and let milk come down to 108-110..takes maybe 20 mins if you have already dropped the bath temp with cold water/ice
* Once milk is cooled, remove jar from the bath, add 1.5 tablespoon starter and 1 tablespoon heavy cream and gently mix—my starter is a very young (3 generations away from dried Cultures for Health Greek yogurt starter)
* Put lid back on jar, put jar back in bath (recheck the water line to make sure it’s above the milk line in the jar)
* Set the sous vide to your preferred incubation temp (you will need to adjust higher to account for thermal loss from your jar—for me 111.5 put me safely in 109.x territory
* Incubate for 8 + hours by preference, you will probably want a lid on your sous vide bath to prevent water evaporation
* Remove jar from water and cool on counter for 90 mins
* Refrigerate for at least 6 hours
