I know everybody does it, and I know there is an inyan to eat dairy, but is there an inyan specifically for eating cheesecake on Shavuos? And if so, where does it come from?
Why do we have a Minhag to eat Milchigs (dairy) on Shavuos?
When is the proper time to eat dairy on Shavuos? (night meal, day meal, prior to day meal, Shul Kiddush)
