I drink store bought nog with spiced rum (whatever's lying around
), with some fresh grated nutmeg on top. I too find it a bit too thick & rich so if the store has a "light" variety I'll get that, otherwise I'll just cut it with ~20% milk.
Ended up making this yesterday. All in all not bad. I suppose it tastes less 'perfumy' and more natural than most of the store bought stuff. I only used 1/3rd cup sugar instead of 1/2 as in the recipe, and it still turned out too sweet for my tastes. Will try less sugar next time.
