Homemade Yogurt
With just two ingredients and five minutes of hands-on time,
you can have creamy yogurt, made just the way you like it.
Live or Active Cultures: These are good bacteria that turn milk into yogurt and give it its texture and tangy
avor. You’ll need live cultures, or yogurt starter, for the rst batch. Any plain, unavored store-bought yogurt
with live yogurt cultures will do. After that, you can use your homemade yogurt as the starter. Science!
Culturing: This is the amount of time it takes for milk and starter to turn into yogurt, anywhere from
8–24hours. The longer it cooks, the tangier it gets. At 16 hours or longer, the tanginess will be similar to
store-bought yogurt. When adding sugar before culturing, we recommend culturing no longer than 16hours.
Milk Protein Skin: As milk heats up, a skin can form on the surface, so stir regularly. There’s nothing wrong
with the skin other than it leaves hard bits in the otherwise smooth yogurt. Just skim off when done cooking.

Before Culturing
• When adding the starter, the milk must be 105–115°F
(41–46°C). If it’s too hot it won’t properly culture (like yeast
when making bread).
• Before adding the yogurt starter to the milk, whisk a small
amount of the heated milk into the starter in a separate bowl.
This way, the starter will be smooth and evenly distribute.
Thick Yogurt
• Place a strainer such as a ne mesh sieve lined with
cheesecloth, coffee lters, or high-quality paper towels
over a large bowl to catch liquid. Then add the yogurt, cover
with plastic wrap, and refrigerate until desired consistency,
about six hours for Greek-style yogurt.
• The liquid that drains off after straining (whey) can be used
in protein drinks, smoothies, soup, marinades, as a starter to
make more yogurt, or as a substitute for buttermilk.
Storing
• Gently spoon into individual portions or storage containers
without stirring.
• You might notice some separation. This is normal, especially
with longer culturing.
• Will stay fresh in your refrigerator for up to two weeks.
Next Batches
• You can use yogurt starter from your homemade yogurt
for up to a week.
• If your yogurt is not culturing as quickly as earlier batches,
the starter may be too weak. Use store-bought yogurt in your
next batch.
