I had this one last night before bed, and adding milk took it to the next level of creamy deliciousness. It was like an egg-less nog, without that heaviness that comes from the eggs and cream.
(Side note: “nog” is such a fun word! Maybe that was part of the appeal.)
I definitely prefer this to actual eggnog (cause I’d rather eat my empty calories than drink them!) It’s very soothing with a mellow spice level, and the rooibos taste is barely present. I think this would also make a great base for a hot toddy with a dash of rum.
