not sure what easiyo is.....I just set a half gallon of milk/yogurt this am. I heated milk up to 180*F, cooled to 110*F and stirred in 2 T. yogurt that was first stirred into about 1/4 cup of withdrawn milk, to temper the yogurt. You don't want to add the yogurt straight to the cooled milk, mix the yogurt first into the heat treated then cooled milk, then add that to the rest of the milk. Incubate for about 8 hours, then carefully put in the frig. Don't disturb until tomorrow morning.
