Unlike most 'proper' cheeses, ricotta is very forgiving and I'm pretty casual with measurements.
2 quarts very fresh
milk, roughly skimmed or cream left on
salt to taste (I'm quite generous)
2.5 tbsp lemon juice
Heat milk to 176f, stirring often to stop it sticking to the pot
Take it off the heat, add juice, swirl pot to mix it in
Milk
should istantly curdle and separate
Leave in the pot till warm, then tip into a cheescloth-lined colander to drain to desired consistency.
Gives you about 350g
I've tried makeing 'normal' ricotta by reheating the whey-it doesn't work
