Faro Recipes

Does anyone have a good faro recipe or better yet a good source on how to brew a faro? I'm wanting brew a faro like you would find at a local pub or brewery in Brussels.

Easiest think:
Brew lambic to taste.
Add sugar cubes into glass when drinking.
This is how it is/was done in belgian lambic cafes by the guests if the lambic is/was too sour.

Once you know how much sugar you like in your glass, you can add sugar to your keg and consume it quickly before it is fermented. You can add more once the initial sugar addition is fermented.
This is how it was done by lambic cafe owners to produce faro for their customers.

All other methods include pasteurization of some kind.
RTFT for more information about pastuerization.
