Using a medium pot over medium heat, bring milk to a temperature of 180°F. If you don't have a food thermometer, this is when a slight film forms at the top of the milk.
Remove from heat and let stand for 3-5 minutes.
Gently stir in the lemon juice and let stand for another 3-5 minutes allowing the curds (milk solids) and the whey (yellow liquid) to separate.
Cover a bowl or line a colander with cheesecloth.
Pour the separated milk into the cheesecloth.
Allow it to drain for a few minutes.
Gently squeeze the cheesecloth to eliminate more of the whey.
Note, for a creamier consistency allow the cheese to remain fairly wet. For a drier, more crumbly consistency, squeeze out more whey.
