It was!
The recipe is Swiss, from a popular series of cookbooks called Betti Bossi, I believe Germans and Austrians have versions as well.
Wähe (pronounced vai-hey) is the base recipe, and the sweet ones are lovely and custardy. There are also savory versions that are more quiche-like.
Is “shot nibble” auto correct for something fun (Shit-gibbon, snot-dribble, etc,) or some obscure southern insult?
