My favorite pea soup was from a crepe restaurant called The Magic Pan. They closed years ago and I still miss it! It was French-style pea soup - Potage St. Germain - served with a splash of sherry or a dollop of sour cream.
Okay, I just got curious enough to Google and found a recipe! Uncle Phaedrus, Finder of Lost Recipes
I may just have to try this one!
