1 liter / 1 quart whole or reduced fat milk (not long life)
4 tablespoons plain, unflavored yogurt with active live cultures
4 tablespoons honey (optional)
8 tablespoons fruit preserves (optional)
Instructions
Place the milk in a saucepan and heat to: 82º Celsius / 180º Fahrenheit (just below the boiling point). Take care to not scald the bottom.
Remove from heat and let cool to lukewarm, around: 40.5º to 43º Celsius or 105º to 110º Fahrenheit (baby bottle temperature).
While the milk is cooling, slightly heat oven for several minutes so it is warm, around 35º Celsius / 85º Fahrenheit. Turn off and leave the oven door closed.
A skin will form on top of the cooling milk. Remove it. Whisk in 4 tablespoons of yogurt. (At this stage, honey may be whisked in, if desired.)
Transfer to clean jars with tight-fitting lids or pour into glass or ceramic large or small bowls and cover with plastic wrap. If using preserves, place in the bottom of the jars or bowls before carefully and slowly add the milk.
Place on a sheet pan. cover with a dish towel. and place in the warm oven. Close the oven door. (Alternatively, place in a warm place or inside a large, plastic cooler.)
Let sit completely undisturbed for 6 to 12 hours. When the yogurt has thickened, carefully drain excess liquid, if necessary.
Place in sealed containers in the refrigerator for at least 4 hours before eating. Use within 4 to 5 days. Serve plain, with granola, topped with fruit, preserves or honey. Don't forget to save a small amount to make the next batch.
If it does not set, either the milk was too hot when the yogurt was stirred in or the cultures were not live in the yogurt. Sometimes lower fat milk will yield slightly grainy yogurt.
Yield: 1 liter / 1 quart plain yogurt
