In a glass/ceramic bowl or a glass jar, mix 2 tablespoons of Prebio Plus with the contents of 1 sachet of LR Superfood Starter.
Stir in 5-6 tablespoons of milk. Mix well with a whisk to avoid clumping. Do not blend with a power blender. The result should resemble a slurry.
Stir in the remainder of the milk. Mix well with a whisk for even distribution. Do not blend with a power blender.
Place in jars and cover lightly with plastic wrap or loose-fitting lids. Don't remove the lids during fermentation to avoid getting a discoloring of yellow or pink on the top of the yogurt. This is a harmless yeast that might affect the taste, so scrape it off the top of the yogurt before consuming it.
Place in a yogurt maker or appliance that ferments at a constant 100°F for 36 hours, away from the airflow of air vents/heaters/air conditioning, etc. Do not stir while fermenting.
When done, remove jars from the appliance, keep the lids loosely on jars, and refrigerate. If you tighten your lids while the yogurt is still warm, it may build up pressure and cause your glass jars to break. Once the yogurt has chilled in the fridge, then you can tighten the lids.
This will keep in the fridge for up to 4 weeks.
